Is this product right for me?
Who is InLei® Lash Form 1 for?
This product is strictly for fully qualified lash lift and lamination professionals. It is the perfect choice for technicians looking to offer a clinically proven treatment that caters to clients of all ethnicities while minimising the risk of allergic reactions.
What is InLei® Lash Form 1?
It is a highly effective primary perm solution. When used as part of the official Lash Filler 25.9 protocol, it is clinically proven to achieve 25% thickening and 9% lengthening of natural lashes over a course of three treatments.
When should you use it?
Use Form 1 after the lashes have been thoroughly cleansed, primed, and secured onto the silicone shields with Fixing Gel. It is the critical "opening" phase that allows subsequent steps to penetrate the hair shaft effectively.
Why choose the Lash Filler 25.9 line?
Because it offers guaranteed, science-backed results. The formula was tested on 40 models of various ethnicities at a clinical institute in Milan to ensure universal efficacy. Additionally, the screw-bottle packaging is specifically engineered to prevent product waste and protect the solution from external oxidation.
To ensure a safe and successful lamination, follow the InLei® protocol:
- Placement: Apply a thin layer of Lash Form 1 using a cat-tongue brush, keeping the product 1.5mm to 2mm away from the roots and avoiding the tips.
- Timing: Leave the solution to work for 6 to 14 minutes, depending entirely on the structure and porosity of the natural hairs.
- Removal: Remove the product carefully with a clean, dry brush before proceeding to Step 2.
- Compatibility: This perm must be used exclusively with InLei® Lash Fix 2 to guarantee the structural integrity of the lash.

FAQs
What is the difference between Lash Filler and LVL?
The LVL is a treatment that just lifts the client's lashes. InLei’s Lash Filler treatment not only lifts the client's lashes but also nourishes the lashes from the inside out. It also helps increase the lashes' natural thickness by up to 24% after just three treatments - which has been clinically proven by the University of Milan.

Can I use the Korean lash lift method with the InLei Lash Filler system?
Yes. The Korean lash lift method can be used alongside the InLei Lash Filler system when performed correctly and professionally. These techniques complement each other and can be adapted depending on lash type, desired results, and treatment goals.

Is Lash Filler a lash lift/lamination?
In short, yes, InLei Lash Filler is a lash lift/lamination treatment, but with the added benefit of nourishing and strengthening the natural lashes. Unlike standard lash lifts, Lash Filler is designed not only to change the curl of the lashes, but also to improve their condition, resulting in thicker, healthier, and shinier lashes.
It is a clinically tested treatment, proven to thicken natural lashes by up to 24%, making it a safer and more advanced alternative to traditional lash lift systems.
Is InLei Lash Filler vegan?
All Lash Filler products are cruelty-free with the majority of products being also vegan. The only product that is not vegan is InLei Filler 3 which contains Keratin, and In Lei Gentle Wax.
How long can I keep the InLei Lash Filler products open for?
Every product has its expiry date listed on the packaging. It is a small open jar icon with the number inside - the number indicates the months.
Bottles:
- Form 1/Fix 2/ Filler 3 - 2 months after opening
- Sachets:
- Form 1/Fix 2/ Filler 3 - it is recommended to use it for a one treatment
How should I patch test for Lash Filler & Tint?
It is always recommended to patch test all products used during a treatment, as they may come into contact with the skin. Apply a small amount of each product to clean skin on the forearm using a clean microfibre brush, leave for 15 minutes, then remove and cover each area with a hypoallergenic plaster. Label each patch so the client can identify which product caused a reaction, if any.
Clients should monitor the area for 24–48 hours and report any reaction. If a reaction occurs, they must be referred to their GP and the treatment should not go ahead.
Tint must be mixed with cream developer for patch testing, as this is one of the most common allergens due to PPD. Always check ingredients during consultation and avoid any known allergens. While patch testing does not guarantee that a reaction won’t occur, it is the safest practice and is strongly recommended for all products, even if not stated in the product leaflet.
My client's lashes didn't lift, why?
There are several reasons why the lashes didn't lift after the treatment:
- Incorrect size of the silicone shield (was the curl too soft/big for the client's lashes resulting in a weak curling effect?)
- The lashes were incorrectly aligned on the silicone shield
- Too much of the fixing gel was used that prevented other products from working
- Incorrect product placement for Form 1 and Fix 2
- Incorrect choice of timing
- Working with expired products
- Working with products that were incorrectly stored
My client doesn’t like the result. Can I repeat the treatment on the same day?
If the effect of the treatment is not as your client has expected, the best solution would be to offer them a complementary treatment in a few weeks' time. If the final result requires an immediate fix, then you can repeat the treatment in the next couple of days, using minimum timing.
However, always take into consideration your client's natural lashes when making a decision, as you do not want to cause any further damage.
How should I clean the lashes after InLei Lash Filler treatment?
Every solution during Lash Filler treatment should be removed using dry cotton buds. We strongly advise you not to use any water. At the very end of the treatment, we recommend using Filler 3 to help dissolve the Fixing gel, and then using the Fillering tool, remove the residue of the fixing gel and tint leftovers from natural lashes. Filler 3 can be left on the lashes and does not need to be removed after the treatment is finished.
As part of the updated InLei Lash Filler 25.9 protocol, you can finish the treatment by cleansing the lashes and eyelid area with InLei Mousse Magica. This professional foam shampoo helps remove any remaining tint and glue residue, releases the shields, and leaves the lashes perfectly clean without affecting the curl or hair structure. It is gentle, suitable for sensitive skin, and helps reduce the risk of allergic reactions.
Does InLei tint contain PPD?
Every hair dye contains PPD, however, InLei Tint contains a very small percentage of it, compared to other brands.
Does InLei tint contain ammonia?
InLei Tint is based on plant waxes and does not contain ammonia.
The InLei tint didn’t stain the skin/the stain washed off after a few days, why?
The stain of the tint on the skin depends on several factors:
- the colour used during the treatment (darker colours tend to leave a slightly stronger stain)
- skin type (colour will fade quicker on oily skin)
- mechanical movements (the use of scrubs, peelings, touching the eyebrows, makeup application etc).
On normal skin, the results can last around 7-10 days, on dry skin up to 7 days, and on oily or mixed skin only up to 3-5 days.
Can I use Lash Filler for an eyebrow treatment?
Yes, you can offer a Brow Filler treatment using InLei Lash Filler products, however, please note that the Lash Filler range of products was designed for eyelashes, and for eyebrows InLei have created the Brow Bomber range.
Brow Filler will influence the brow hair structure, resulting in thicker hair up to 24% in 3 treatments. It is important to remember that not every client would like to have their eyebrow hairs thicker.
Is InLei Brow Bomber a brow lamination/brow perm treatment?
Yes, Brow Bomber is a name used to describe a brow lamination/brow perm treatment that is performed using InLei Brow Bomber products.
What is the shelf life of the InLei Brow Bomber bottles?
Every product has its expiry date listed on the packaging. It is a small open jar icon with the number inside - the number indicates the months.
- Brow Lift 1 - 3 months after opening
- Brow Lock 2 - 3 months after opening
- Brow Bomber 3 - 9 months after opening
- Mister Fix is made with an airless bottle that prevents contact with oxygen, extending the shelf life of the product, keeping it perfect for up to 12 months!
Can I use henna instead of tint for InLei Brow Bomber?
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.
What are the steps to use Brow Bomber?
Disclaimer: Brow Bomber products are for eyebrow treatments only performed by a trained professional.
STEP 1: PREPARE THE EYEBROWS
STEP 2: APPLY INLEI® "BROW LIFT 1"
STEP 3: SHAPING THE EYEBROWS

Can I use InLei Brow Bomber 3 on its own?
InLei Brow Bomber 3 is a product designed to be used as the last part of the Brow Bomber treatment to finish the treatment and complement the previously used products, which can be quite drying on the eyebrow hairs.
Used on its own, it does not give a brow lamination effect, and will only act as a moisturising, nourishing butter. It can be used as the last step of the tinting procedure to nourish the eyebrows.
Brow Bomber 3 is for professional use only.
Can I use InLei Filler 3 instead of InLei Brow Bomber 3 for eyebrows if my client is allergic to InLei Brow Bomber 3?
Both Lash Filler and Brow Bomber ranges have been designed to work together within their own range of products. That is why we wouldn't recommend mixing products from another range, as we cannot guarantee the results.
Can I use InLei Brow Bomber on eyelashes?
No, the Brow Bomber range has been designed specifically for brow lamination, and should not be used on the lashes, as it may cause damage.
Should I use cling film with InLei Brow Bomber instead of the Fixing Gel?
We recommend using Fixing Gel to align the eyebrows during Brow Bomber treatment. This will help you control the directions of hairs and create the desired effect. We do NOT advise using cling film for Brow Bomber treatment, as Brow Bomber is a cold perm, therefore it should not be exposed to a higher temperature during processing time (higher temperature is created when brows are covered with a cling film, which speeds up the processing time - this may cause damage to eyebrow hairs).
Can I use a different brand of tint with InLei Brow Bomber?
All products from the Brow Bomber range have been designed to work together, in order to guarantee sufficient results. If you decide to use another tint brand, you may not have the same effects as when using all products from the collection.
