How does Step 1 of lash lifting and lamination work?

Natural eyelashes or eyebrow hairs maintain their shape, among other things, thanks to disulphide bonds in the keratin structure.

If we want to change the curl of the eyelashes during lash lifting or change the growth direction of the eyebrow hairs during lamination, their structure must first become sufficiently pliable.

This is exactly what Thuya Permanent Gel – Step 1.

Its active ingredient is TGA, which acts on the disulphide bonds during the first step. The hair becomes more flexible, allowing the stylist to prepare it for a new shape.

However, the process does not end with the first step. Subsequent neutralisation in Step 2 is an essential part of the system.

TGA – thioglycolic acid as the active ingredient

Thuya Permanent Gel works on the basis of TGA – thioglycolic acid.

This is the active component of the first step, which allows the change in hair structure required for professional lash lifting and brow lamination.

Permanent Gel is characterised by the manufacturer as a strong preparation, therefore it is important to monitor the progress of the procedure and not rely solely on the maximum stated processing time.

Time is not the only factor. The curl test is decisive

The approximate processing time for Thuya Permanent Gel is 7–15 minutes.

However, this does not mean that every type of eyelash or eyebrow hair requires the same 15 minutes.

What is decisive is the disulphide bond breakage test – curl test, which the professional uses to check if the hairs are sufficiently prepared for the next step.

This is particularly important with a strong first step, as the structure of natural hairs varies between clients.

7–15 minutes is an approximate time range, not an automatically set time for every client.

Thuya Permanent Gel for lash lifting

For lash lifting, Permanent Gel serves as the first chemical step after the natural eyelashes have been correctly positioned.

Its role is to prepare the eyelashes for a change in their original shape, making it possible to create the desired curl according to the chosen silicone form and the stylist's technique.

Once the desired level of processing is achieved, the Permanent Gel is removed and followed by 2nd neutralising and fixing step.

Thuya Permanent Gel for eyebrow lamination

Permanent Gel can also be used for professional eyebrow lamination.

During brow lamination, it increases the flexibility of the natural eyebrow hairs, allowing them to be directed into the desired position.

When used on eyebrows, a combination with a suitable protective balm.

The resulting direction of the hairs is then stabilised using Thuya step 2.

Pre-smoothing before the first step

Before the application of Permanent Gel, a preparatory step to soften the hairs can be included according to the professional protocol.

Thuya has separate products for this purpose depending on the treated area:

Thuya Pre-smoothing of Eyebrows – a preparatory solution to soften eyebrow hairs before lamination.

Thuya Pre-smoothing of Eyelashes – a preparatory solution to soften natural eyelashes before lash lifting.

These products are used before the application of the first step, not instead of Permanent Gel.

Usage

1. Apply a small amount Thuya Permanent Gel approximately the size of a grain of rice onto an application wand.
2. Apply the product to the centre of the eyelashes or to the eyebrows.
3. Cover the treated area with osmotic film.
4. Cover with a headband.
5. The approximate processing time is 7–15 minutes. Monitor the progress using the curl test.
6. Remove the product a dry cotton bud.
7. Continue with the compatible 2nd step Thuya Neutralizer Cream or Thuya Neutraliser.

What to combine with Thuya Permanent Gel?

Permanent Gel is 1st step of a professional system, therefore it is not used as a standalone procedure.

After its use, it must be followed by:

Thuya Neutralizer Cream – creamy 2nd step

or

Thuya Neutraliser – liquid 2nd step.

Before the first step, the corresponding Thuya Pre-smoothing product can be used according to the procedure.
