Which glue is the fastest?

Our fastest glues are Power Bond and Royal Bond, and they both are drying in 0.5-1 second if used in their recommended temperature and humidity range. 

Power Bond works best in 18-22°C (64.4 - 71.6°F) and 50-65% humidity.

Royal Bond works best in 18-22°C (64.4 - 71.6°F) and 30-80% humidity.

Remember, that the higher the humidity in your room, the faster any glue works! Please note that both of the adhesives are extremely fast and should be used only by HIGHLY EXPERIENCED technicians. Incorrect work with fast-drying adhesives can cause retention problems.

Which glue is best for me?

The best lash glue for you will depend on a few different factors. As a beginner, you’ll be looking more at glues like Lady Bond or Satin Bond which have a more gradual drying time. Check out our glue comparison table for a complete guide to picking your glue. 

For the most accurate suggestion, you’ll need to know

Your room temperature

Your room humidity

How long it takes you to place an extension on the natural lash after you’ve dipped it into the glue

So it’s worth investing in a hygrometerto keep an eye on your typical room conditions.

Retention Issues

Have you found your client's lash extensions are falling out after a few days, or you’re experiencing ‘brush-offs’ during your lash set? Here is a retention checklist to make sure that your client’s lashes are applied correctly and last as long as possible:

Make sure natural lashes are cleaned very well prior to the treatment. Use Lash Shampooand Protein Remover Pads to clean the eye area from any makeup, dust and oils. Then prepare the natural lashes using Cleanser and Primer.

Use Booster to improve the speed and retention. Booster due to its alkaline pH opens the cuticle of the natural lashes and improves the glue bonding power. Also, Booster speeds up the treatment as glue polymerises faster with it. 

Ensure that your attachment is always spot on: there is enough glue to hold the extensions and that the base of the extension (at least 2mm) is fully attached to the natural lash.

Ensure your hands are not shaking. As the glue dries in seconds, the application should always be steady and accurate. Do not touch the lash once you have placed it on the natural lash. Allow the glue to dry and form a strong bond with the natural lash. Do not brush out the lash extensions as soon as you have placed them. 

Always work with a fresh glue drop and shake the glue before each use. Ensure your glue is stored correctly and is not expired.

Work with a glue that is suitable for your experience and work conditions.

Use Superbonder to polymerise the glue and add elasticity. Elastic glue is less likely to snap off/chip off the natural lash. Also, after using Superbonder, clients can make their eyes wet straight away without the risk of shock polymerisation and retention problems caused by it. 

Make sure your clients are following the aftercare advice and are not picking the lashes and are keeping them clean. We have online aftercare leaflets available to purchase so that you can ensure you’re giving your clients clear instructions on how to care for their extensions.

Wearing masks for a long period of time (during and after appointments) may influence retention.

 Spring/Autumn lash shed - during those periods clients experience a natural shedding where more lashes are naturally falling out.

Changes in weather - during Winter/Autumn time we start to use heaters that are increasing room temperature but also decreasing the humidity, which creates a difficult environment for the glue.

Your Glue Is Causing Bad Retention? It’s A Myth!

For more help with any lash retention troubles, get in touch with our customer care team at, who are always on hand to help!

Which glue is suitable for sensitive eyes?

All our glues contain the same active ingredient, which is cyanoacrylate. The majority of allergic reactions are caused by the fumes of cyanoacrylate. If a client has experienced a reaction, the likelihood is now they will always be allergic. That is why we do not recommend performing a treatment on a client who had previously developed an allergic reaction to the adhesive or is showing any signs of the reaction.

If you perform a treatment on a client with contraindications to the treatment, you may not be covered under your beauty insurance.

Clients who experience just mild discomfort from the glue fumes may benefit from reducing the fumes with Superbonder at the end of the treatment. 

Another tip will be to reduce the glue fumes around the client’s face by using the Glamcor Flow to extract the glue fumes and improve the air quality.

My glue is drying too slow

Your room conditions may be affecting the polymerisation process of the adhesive. 

We would suggest trying to increase the humidity in the room for faster adhesive polymerisation and adjusting your temperature accordingly. You can also use Boosteron the lash strip and on natural lashes to increase the speed of polymerisation and improve the retention.

We would highly recommend to purchase a Hygrometer to monitor your room conditions and ensure you are working within the optimal room conditions for your adhesive. 

Here are a few tips on how you can increase the humidity in your lash room/salon:

Place a damp towel over the radiator
Get a humidifier - you can pick up cute little ones on the internet, and for an added little touch of relaxation and luxury for you and your clients, you can add a little drop of essential oil to give out a delicate scent!
Add some little droplets of water along the eyepatch using a microfibre brush
Apply Primer in sections as you work to keep the lashes moistened

Alternatively, if you have been lashing for a while, you may simply have improved your lashing speed! In this case, your lash glue may now be too slow for you. Why not consider testing out a faster-drying adhesive?

My glue became gloopy, why?

There are a few reasons why your glue could become gloopy, however, it usually comes down to incorrect storage and care of the bottle itself. 

Here is a little checklist to prevent it from happening:

Ensure your glue is not expired and that it was stored correctly in a cool, dark place, away from direct sunlight and protected from humidity

Ensure that no residue glue in the nozzle has been pushed back into the glue bottle - this may ruin the rest of the glue

Check if your glue has not been opened for longer than 8 weeks

Ensure you close the glue correctly straight after pouring out the drop of glue as otherwise, the glue can start changing its consistency 

Do NOT wipe the nozzle with a wet wipe as it may cause the glue in the bottle to become gloopy

If you require any assistance with your lash adhesive, get in touch with us by emailing including your order number with a description of the problem.

My fans are closing, why?

The number one reason why your Russian Volume fans will be closing from the point of dipping them in the lash glue, is simply that your lash glue is drying too slowly for you.

We would first recommend reviewing the necessary room conditions for your glue and adjusting accordingly to increase the temperature and humidity. A great solution to prevent fans from closing and control and improve the bonding process is using Booster on the lash strip before you pick off the lashes to create your fans. You can also apply Booster to the natural lashes to increase the porosity and ensure the lash glue does not travel. 

We also recommend checking the amount of glue that you are picking up, as using too much adhesive can also cause the fans to close.

How do I clean my glue nozzle?

Use a glue nozzle wipe to wipe off the glue from the nozzle after every use. Keep the bottle in an upright position and squeeze the bottle gently to get glue residue out of the nozzle. 

When shaking the glue by hand, make sure to remove the cap first, and cover the nozzle with a glue nozzle wipe. This will prevent the glue from getting stuck in the cap. 

When shaking the glue with a glue shaker, ensure to hold the glue shaker in an upright position so the bottle is facing vertically (with the cap at the top) and when finished, remove the cap and wipe the nozzle with a glue nozzle wipe.

For more information on the correct storage of your lash glue, read our Glue FAQ blog!

What is the shelf life of the glue?

The shelf life for our glues before opening is 6 months from the date of production. This can be found printed on the bottom of the bottle or the foil pouch the glue arrived in.

After opening a glue bottle, we recommend changing your glue bottle every 4 weeks for the best retention, and maximum every 8 weeks. To keep an eye on the freshness of your glue, simply stick a piece of tape with a written date when you open your glue.

My glue nozzle got blocked, what do I do?

You can purchase a spare nozzle to replace the blocked nozzle. If the nozzle got stuck to the cap, we recommend trying our Glue Rescue Kit

To prevent it from happening in the future, please ensure to clean your glue nozzle after every use, always store your glue correctly, and do not squeeze the bottle to dispense a glue drop.

My glue bottle has a white residue, why?

The white residue on your glue bottle is adhesive that has shock polymerised due to exposure to moisture. This may be caused by not storing your glue correctly or by not fully closing the glue cap. 

Please ensure you always store the glue in an airtight container, away from direct sunlight and that the glue cap is always fully attached to the bottle.

My glue appears clear, is it normal?

Every glue should be shaken for at least 1-2 minutes prior to use for the ingredients to mix. If you are using a Glue Shaker this time will be cut down. 

Unless you are using Crystal Bond, which is a clear glue, your glue drop should always be black without any traces of transparent liquid. Ensure you shake the glue not only before the first use of the day but also each time you open it to refresh your glue drop.

Why can’t I order more than 10 pieces of glue?

We have limited the number of units for purchase of each variant of glue per customer, per order, to 10 pcs to reduce the possibility of overstocking on a perishable product.

The shelf life for our glues before opening is 6 months from the date of production. This can be found printed on the bottom of the bottle or the foil pouch the glue arrived in.

After opening a glue bottle, we recommend changing your glue bottle every 4 weeks for the best retention, and maximum every 8 weeks.

If you have any questions or queries on this, or would like to order in bulk, please contact our customer service team who will be happy to help you. 


Do you sell mink lashes?

All our lashes are made from synthetic material so are completely cruelty-free and hypoallergenic, they are soft and lovely to work with.

We do have two main collections: Mayfair Mink and Chelsea Silk but the names are only used to differentiate between the collections. Both are still made from synthetic materials. The main difference is in the way the lashes are finished - the Mayfair collection has a shinier and darker appearance than the Chelsea. Chelsea is a great option for clients looking for a more natural volume set or classic lashes, whereas Mayfair is a bolder, darker option which will give a more dramatic and glamorous finish. 

The strip that the Mayfair comes on is also a little bit less sticky, so some lash technicians prefer this for creating fans, depending on their favoured fanning method. For classic lashes, Mayfair and Chelsea are both well-loved by lash artists and their clients alike. 

What are the best eyelashes to buy?

The best lashes for you will depend on your preferences and the look you are hoping to achieve, but in quite general terms our best-selling Classic lashes are 0.12 and 0.15 thicknesses.

For Russian Volume sets, our 0.05, and 0.07 are well-loved! Or if you're after those super fine lashes for mega volume looks we have 0.03 and 0.04.

Almost all lashes are available in mixed and single lengths trays so that you can either try out a bit of everything or get all of the lengths you love best and use the most. We have a few different curls on offer, but the best-sellers are C, CC and D curls across all ranges, and a new love M-curl!

To find out more information on our lash extension range, read our blog: Different Types Of Eyelash Extensions And When To Use Them or for beginner lash artists, check out our blog on How To Pick The Best Lash Supplies As A Beginner!

What is the maximum thickness you would recommend to create volume fans?

When choosing the thickness for volume lashes, we need to take into consideration few factors:

Thickness of client’s natural lashes

General condition and health of client’s natural lashes

Final effect you want to create

The more volume you want to create, the thinner the lashes you will use should be. Mega volume fans = thinner lash extensions

For 2D volume, we recommend either 0.10 or 0.07 thickness.

For 3D-5D volume, we suggest 0.07 or 0.05 thickness.

For volume 6D or more we recommend 0.05, 0.04 or 0.03 thickness depending on the final effect you want to achieve. 

Please also remember that if you would like to create longer looking lashes, it is good to then reduce the amount of volume, to keep the client's natural lashes in good condition.

For more training on how to create Russian Volume fans take our Online Russian Volume Course!

What lashes are best for creating a volume set?

All our lashes, except for Matt Flat Ellipse lashes, are perfect for creating a gorgeous volume lash set. It is the lash technician’s personal preference, if they would like to use Chelsea or Mayfairlashes, as both collections can be used for creating fans.

We also sell Easy Fanning Lashes that have mixed lengths on the strip to create an effortlessly easy wispy effect.

Alternatively, you can use Premade Fans which have been handmade already in the factory, allowing you to create a quick volume application, without spending time on creating fans.

What lashes are best for classics?

It is the lash technician’s personal preference if they would like to use Chelsea or Mayfairlashes, as both collections can be used for classic sets. We sell a variety of thicknesses ranging from 0.12 to 0.20 so you can choose the most suitable thickness. 

You can also use our Matt Flat/Ellipse Cashmere Lashes, that due to their ellipse shape create a slightly thicker looking and more dramatic classic set. Due to their flat base (instead of the rounded base with the Mayfair/Chelsea range) it help to create a better bond between the natural lash and the eyelash extension. Additionally, Matt Flat Ellipse lashes have a split-tip, creating an even softer wispiness to a classic lash set.

What are your lash extensions made from?

All London Lash Pro lashes are made from a synthetic material so are completely cruelty-free and hypoallergenic, they are beautifully soft and lovely to work with.

What is the difference between the Mayfair and Chelsea collections?

The Mayfair Mink lashes are made from the same synthetic material as the Chelsea Silk, meaning that they are hypoallergenic, hold their curl perfectly and last equally well! The main difference is in the way the lashes are finished - the Mayfair collection has a shinier, darker and bolder appearance than the Chelsea, which is a more natural lash colour and perfect for creating a beautiful soft natural look. The strip that the Mayfair comes on is also a little bit less sticky, so some lash technicians prefer this for creating fans, depending on their favoured fanning method. For classic lashes, Mayfair and Chelsea are both well-loved by lash artists and their clients alike.

To see the lash collections for yourself, watch our video London Lash Chelsea, Mayfair, and Flat Lashes

Which glue should I use when working with Colour lashes?

Clear glue is the best friend for coloured lashes, especially lashes which are light in colour, for example, light blue, pink or white!. To create a bright and colourful look that truly pops - use a clear adhesive. This way the bonding won’t be visible, which is especially helpful when using bright colours. Our Crystal Bond adhesive is the perfect choice for this!

Alternatively, you can use a black adhesive to create a more defined eyeliner effect. When working with darker coloured lashes, for example, dark blue or brown - try using black glue. You will be surprised how easily you can achieve an eyeliner effect this way.

P.S. Make sure your glue application is spot on, as it will be more visible with coloured lashes!

Which of your lash collections are the softest?

All of our lash collections are made from a super-soft synthetic material.
We have various lashes in our range - 

The Mayfair (Bold Finish)

The Chelsea (Natural Finish)

Matt Flat / Ellipse Lashes

Premade fans

Easy Fanning Lashes

Naturally, the more you go up the thickness of the lash extensions, i.e 0.20 thickness, the lashes will feel harder in comparison to a thinner lash, i.e 0.03, 0.05 or 0.07. 

For classic lashes, why not choose our Matt Flatt Ellipse lashes that have a split-tip, which makes them super-soft and perfect for wispy classic sets!

For more information on which lashes to choose, read our blog!


How should my clients wash their lashes?

It is always best to recommend to your clients to use a professional product that has been designed and tested to be in contact with the gentle eye area. Our Lash Foam Shampoo has been tested and approved to be used together with eyelash extensions, it removes makeup and prepares lashes for the application. Additionally, it will clean the lashes by removing any oil, sweat and makeup build-up which will help to keep the lashes on longer. 

Baby Shampoo or other products not made specifically for the eye area or lash extensions, in particular, should not be used on the eye area, and quite often can actually cause dryness or irritation on the delicate skin around the eyes.

My client’s lashes are clean but I still have problems with retention, why?

If you are experiencing retention issues make sure to check if you follow all the steps of pre-treatment correctly. Very often lashes that seem ‘clean’ are not thoroughly cleaned and may be causing retention issues. Make sure to always follow a full pre-treatment routine and refer to our glue section to check if you follow all recommendations for the correct work with the adhesive. 

Find out more on how to slay a full pre-treatment routine

Lastly, make sure that your client is also following the lash aftercare as this may also have an impact on the retention.

What is the difference between Booster and Superbonder?

Retention & Speed Booster is a multi-functional product that will enhance your treatment as it increases retention and the speed of work. Due to its high alkalinity, Retention & Speed Boosterhelps to gently open the hair cuticles. This enables more glue to stick with the extension and the natural lash thus increasing retention. Apply Retention & Speed Booster with a micro brush on natural lashes, after cleanser and primer to slightly open hair cuticles and increase the surface for better grip and adhesion. 

Watch a tutorial on how to apply Booster during a treatment:

Superbonder adds elasticity to the adhesive. The additional flexibility ensures the bonds don't break as easily, therefore resulting in better retention. Superbonder instantly polymerises the glue, without shock curing. It locks in the fumes from the adhesive and with the fumes contained, irritation and sensitivity are significantly reduced. Additionally, because the bonds have been sealed, the lashes are instantly safe to get wet. So no more waiting 24 hours after the treatment! 

What is the difference between Cleanser and Primer?

London Lash Cleanser is an alcohol-based product that is used to de-moisturise natural lashes and removes any oils and proteins from their surface. London Lash Primer is a water-based product that is used to moisturise natural lashes and neutralise pH levels to improve the bonding between the natural lashes and the extensions.

It is not recommended to use Cleanser without the Primer. This is because the Cleanser is very drying on the lashes, and without moisture, the lash glue will not be able to cure. The Primer must be used after cleansing, as it puts moisture back into the lashes after the high alcohol content of the Cleanser.

For an extra touch of luxury, why not go for one of our scented Cleansers and Primers? It’s such a little thing, but a slight waft of Cherry or Coconut can take your client’s experience from an 8 to a solid 10!

What is your recommended pre-treatment routine for the best retention?

How you complete your pretreatment has as much of an effect on the retention of the lashes as the glue you use. It can be the difference between 2 weeks of retention, and 5 weeks of retention, so it is very important to get it right - lash retention is client retention, after all!

The very first step should always be makeup removal. You can either give your client a lash bath with a Lash Foam Cleanser to wash their lashes or you can hand them the foaming cleanser so they can wash their lashes themselves in the bathroom. 

After removing all makeup, follow the next pretreatment steps to ensure natural lashes are well prepared:

Step 1: Use Protein Remover Pads - If there are some remnants of mascara, makeup, oils or sebum build-up around the lashes, the protein remover pads will do an excellent job at ensuring all final traces of unwanted oils are removed.

Step 2: Use Cleanser - Cleanser has a high alcohol content which gets rid of EVERYTHING - any oils, any residue from foam cleanser that might be left, any little tiny traces of makeup will be gone. 

Step 3: Use Primer - It is a MUST to use Primer after Cleanser because it puts moisture back into the lashes after the high alcohol content of the Cleanser which can be drying. It gets those lashes ready to have extensions placed on them like nothing else.

Step 4: Booster! - Booster may be considered a London Lash holy grail product, and it’s for good reason! Natural lashes can be smooth and silky, which can result in extensions ‘sliding off’. Due to its alkaline qualities, Retention and Speed Booster gently opens the hair cuticles without damaging the natural lashes, enabling the glue to grab on the cuticles and hold better, improving your retention. 

Ta-da! Now you’re ready to go. Get that map drawn and slay some lashes! 

Watch our YouTube video on how to perform a full pre-treatment routine and get the best retention possible!

Can I use only a Cleanser to prepare lashes?

We always recommend completing all steps of pre-treatment in order to increase retention and ensure that lashes are super clean. We also would not recommend using a lash Cleanserwithout following with a lash Primer. This is because lash Cleansers have high alcohol content in order to completely remove any oil residue on the lashes, which can be very drying to the natural lashes. You will need to follow with a lash Primer in order to replace that lost moisture so that the lash glue has some moisture in order to dry. Without some moisture, the lash glue may be drying too slow for you, or not at all! 

To properly prepare natural lashes, check out some articles and videos on how to slay pre-treatment for that 5-week retention goal!

Can I use a saline solution in order to clean the lashes?

Saline solution, whilst a great option to clean lashes in a hurry, doesn’t always remove all traces of oil and makeup build-up, which can drastically affect your retention. 

We always recommend completing all steps of pre-treatment in order to increase retention and ensure that lashes are super clean. How you complete your pretreatment has as much of an effect on the retention of the lashes as the glue you use. It can be the difference between 2 weeks of retention, and 5 weeks of retention, so it is very important to get it right - lash retention is client retention, after all!


Which tweezers do you recommend for Classic Lash extension sets?

There are two ways of using classic tweezers:

1. Using straight tweezers for placing the lash extensions and curved tweezers for isolation

2. Using straight tweezers for both placement and isolating

The choice depends on your personal preferences, as both ways are correct no matter whether you use straight or curved tweezers for isolation. We have a wide range of straight and curved tweezers that differ slightly by length and final shape.

Which tweezers do you recommend for Russian Volume sets?

We have two types of volume tweezers available in our store:

1. Fine Tip Deluxe Tweezers

2. Regular Tip Volume Tweezers

Both types have been designed for the perfect fan creation and it is totally up to you which one you choose, as it is down to personal preference which shape one may prefer. However, our best selling volume tweezer is Fine Tip Deluxe!

Both volume tweezers are perfect for making fans up to 8D, and the Fine Tip Delxue Tweezers up to 10D fans! However, it entirely depends on your own experience and training. Practice makes perfect!

Which eyepatches are best for smaller eyes?

To precisely apply eyepatches to small eyes, we recommend a smaller shape of eyepatches so they will nicely fit and will not cause any discomfort for your clients.

You can either choose Nano Hydrogel Eyepatches that are very thin and flexible to suit every eye shape. They contain plant extracts that are known for boosting microcirculation, antioxidant and anti-allergy properties, leaving the skin looking healthy and radiant.

Another amazing solution would be Teflon Eyepatches which work especially well for small eyes, oily skin or deep-set eyes. Due to an innovative bottom gel, they stay in place throughout the whole appointment. They also have a specially formulated top surface that creates a non-sticky layer to help prevent extensions from sticking to the patch when working with clients who have downward-growing natural lashes.

One (1) year unlimited unconditional warranty for manufacturer's defect, loss of functionality, parts, shipping, and service. After one year we will continue to warranty the product provided we have the parts to repair and/or replace.

To check which products are Vegan, Gluten-Free and Halal please visit each product listing and check under ‘Product Properties’. 

How should I store my products?

Depending on the product type you may want to store certain products slightly differently, however, we always recommend to store them in a cool, dry place, away from direct sunlight.

And to be a bit more specific for some most important products:

Glue : always keep your glue away from direct sunlight and protect it from high temperature and humidity. We recommend storing you glue in an air tight container.

Lashes : keep them in original lash boxes, stored for example in a cupboard , unless you are using them. Then we recommend preparing a few palettes and keeping them in a closed acrylic organiser to protect from dust.

Tape : always protect the tape from dust by keeping it in a tape cutter or any other closed container.

Micro brushes/brushes : always protect them from dust by keeping them in a closed acrylic organiser or any other closed container.

What are your regulations on patch testing?

When it comes to patch testing, this is something which is strongly advised but not something you necessarily need to enforce. We recommend checking with your insurance provider if they require you to perform a patch test in order to cover you for the treatment.

A patch test should always be carried out at least 48 hours prior to the treatment by applying a few lashes per eye, the same way you would normally do when performing a treatment. It is usually around 10-15 lashes per eye, the same length as natural lashes, so they nicely blend in.

Few important things to remember:

- If the client has had extensions before and has had no reaction, they may still have one at any given time, as allergies can develop over time.

- If a client has not had extensions before and does not know whether they are allergic or not, it is of course advisable to conduct a patch test, but please be aware that they may still have a reaction due to a lower amount of adhesive being used.

- Patch testing on the skin is not advised but it is quite an old-fashioned way of conducting a patch test, from when eyelash extensions were new and not really widely known. The glue should never be applied on the skin as it may cause redness or irritation almost immediately, which may not necessarily be an indicator for an allergic reaction. The glue can also cause serious burns when in contact with the skin.

- Always check with your insurance provider what is their policy regarding patch testing.

- Always inform your clients that they may still develop an allergic reaction despite having a patch test done, as allergic reaction to glue fumes is a developed allergy and can happen at any point while having your lashes done (even after many years).

- We strongly advise NOT to perform a treatment, if your client shows any signs of an allergic reaction, or you are aware of an allergic reaction that happened in the past.

Is it safe to do lashes on pregnant clients?

This is something which is down to the individual salon/lash technician/client/insurance. When performing a treatment on a pregnant client there is a risk that in the event of an allergic reaction, the client wouldn’t be able to have any medicine to reduce the symptoms. We always recommend checking with your insurance provider if they cover you in the event of working with pregnant clients and making an individual decision based on that.

Do you have a physical shop?

We do not have a physical shop, we are an online-based company.

My client had an allergic reaction, can I do their lashes again?

Unfortunately no, because if a client has developed an allergic reaction once, they are more prone to develop it in the future. You may also not be covered under your beauty insurance if you perform a treatment on a client with contraindications to the treatment

Clients who experience just mild discomfort from the glue fumes may benefit from reducing the fumes with Superbonder at the end of the treatment. 

Another tip will be to reduce the glue fumes around the client’s face by using the Glamcor Flowto extract the glue fumes and improve the air quality.

Why can’t I order large quantities?

We have assigned maximum limits to our product selection on our websites for a few key reasons:

- To avoid customers facing any potential overstocks from bulk buying and the products then reaching its expiry date before use (especially the glues!)

- To avoid buying for resale 

Our returns policy states that we cannot accept any returns for unwanted products over 14 days since purchase, and so unfortunately we would not be able to accept any returns over this period if you accidentally overstocked from bulk buying during the sale. The last thing we want is for our customers to lose out, so we have this policy in place to safeguard against any potential disappointments.

What is the difference between brow Henna and Tint?

Henna is a dye created from the plant Lawsonia Inermis. The orange dye present in the leaves of the henna plant, chemically reacts with the keratin in the skin and hairs, resulting in a strong stain that lasts until the skin or hair changes. Eyebrow henna is the commercial name for products used as a brow colouring solution, however, it may not always be derived from the henna plant. Eyebrow henna is a powder that is mixed with water into a creamy paste that is then applied to the eyebrows.

Eyebrow tint is another form of dye that is widely used in lash and eyebrow colouring. It is usually the consistency of a gel/cream and needs to be mixed with an oxidant (hydrogen peroxide) in order to be activated. Once applied to the eyelashes or eyebrows, colouring agents bond with keratin and start the tinting process. 

How can I achieve the brow lamination effect using So Henna?

You can use the So Henna Brow Soap to finish off the treatment to imitate the effect of brow lamination. However, please bear in mind that brow lamination itself should never be combined with henna brow treatment.

Can I use henna for brow lamination treatment?

Henna dye cannot be used for Brow Bomber (brow lamination) treatment. Both henna and lamination slightly dry out the eyebrow hair and when combined together can cause damage to the eyebrows. 

You should wait at least 20 days after brow lamination to offer a henna brow treatment. For brow lamination, it is recommended to use tint.

Are So Henna products vegan?

So Henna products are:



Halal certified

low in PPD


hydrogen peroxide free

eco friendly 

How long does it take to perform the treatment?

So Henna should stay on the eyebrows for 8 to 20 minutes, depending on the desired results. With pretreatment, colouring and shaping the treatment takes approximately 30-45 minutes.

The time may vary depending on each client and the final result you are achieving.

What is the best way to prepare the skin for henna brow treatment?

1. Remove any makeup and wash the eyebrows with cleansing brow soap.

2. Make sure not only to clean the eyebrow hairs but also the skin around, so you have a clean area to work with.

3. Wipe it off using damp cotton pads. For an extra deep cleaning to ensure you get the best colour/skin stain payoff, you can also go in with the London Lash Protein Pads to remove any oil/shampoo residue and ensure the area is super clean and ready for application.

4. Gently scrub the eyebrows and the skin around using a soft brow scrub.

5. Wipe it off using damp cotton pads.

6. Brush the eyebrows and you are ready to start the treatment!

How is So Henna different from other brow henna powders on the market?

So Henna was developed by the best brow specialists in the industry - from brow artists to brow artists! It can be applied in only ONE layer when you usually need multiple layers when using other brands. This speeds up the treatment time and makes the application much easier.

So Henna colours can be used individually or mixed to achieve a perfect custom colour.  Additionally, the colours do not result in a warm/orange colour payoff, unlike other brands on the market, and the final result can last up to 6 weeks on the hairs!

What can I mix So Henna powder with?

Add a little henna powder to a non-metallic container and mix with a few drops of distilled water. Ensure all powder is incorporated and leave to stand while you prepare the skin.

Why should I use distilled water for the So Henna treatment over regular tap water?

It is always recommended to use distilled water to mix with the So Henna power, as it is more hygienic to use on clients as any contaminants have been removed, as well as any other minerals in the water which may affect the final result of the Henna.

How long does henna last on the hair and skin?

So Henna lasts on the client's hair for up to six weeks, depending on the natural hair growth cycle, and lasts for up to two weeks on the client’s skin.

The colour stain on the skin and how long it lasts depends on several factors:- the colour used during the treatment (darker colours tend to leave slightly stronger stain)- skin type (colour will fade quicker on oily skin)- mechanical movements (the use of scrubs, peelings, touching the eyebrows etc).

Remember: brow henna treatment is primarily a brow colouring treatment and any skin tint is simply an added benefit, it is not always guaranteed!
