What is the Keratin Alpha Sleek Range?
What is Alpha Keratin?
It is the primary protein that forms the very core structure of your hair, residing at the deepest level of the fibre. It is the building block that dictates each strand’s shape, strength, and elasticity.
Why does Alpha Keratin determine the hair’s outer shape?
Alpha-keratin is the fundamental structural protein that forms the hair. Its internal helical arrangement, along with the extensive network of bonds within the hair’s cortex, dictates the strand’s overall geometry, and ultimately determines if hair appears straight, wavy, or curly.
What hair needs does this franchise address?
Keratin Alpha Sleek range has been formulated with stylists for all those who want to reduce frizz, improve smoothness, and keep hair straighter and softer, with results that last. In fact, while other at-home smoothing treatments only act on the surface of the hair for a temporary result, Keratin Alpha Sleek transforms hair at Keratin Alpha level, to reprogram hair for up to 2 weeks of frizz control*, ensuring daily styling in half the time**. It is suitable for all hair types.
Does the Keratin Alpha Sleek range contain keratin?
Keratin is an animal-derived ingredient, also found in human hair. These products don’t contain keratin, but reprogram hair from deep inside the fibre at the Keratin Alpha level, reshaping Keratin Alpha chains for up to 2 weeks of frizz-controlled hair*.
What is the Keratin Alpha Sleek Smooth Transformer?
What is the Smooth Transformer?
It is an at-home treatment that helps reduce frizz, boost smoothness and shine, and keep hair straighter and softer for longer. Designed with professionals, it is a unique hybrid between a haircare product and a smoothing treatment. It acts at the deepest level of the hair fibre – Alpha Keratin Level - where it reshapes the Alpha Keratin chains for up to 2 weeks of frizz-controlled hair*.
How well does it really control frizz compared to other at-home treatments?
Other at-home usage treatments often only act on the surface of the hair for a temporary result. The Smooth Transformer, on the other hand, reprograms hair from the Keratin Alpha level. This leads to longer lasting results compared to traditional at-home treatments.
How do I use the Smooth Transformer?
For what hair types does the Smooth Transformer work?

Apply it once a week [AKA every 3 washes], for 4 weeks, after the Keratin Alpha Sleek Shampoo. Give the formula 15 minutes to act deep from within hair fibres. Rinse thoroughly, then apply the Keratin Alpha Sleek Mirror Sleek Serum. For best results, finish with heat styling to lock in the benefits. The Smooth Transformer is a progressive smoothing treatment - should you wish to use for an extended period we recommend you to have a consultation with a professional hairdresser.
How much product should I apply?
We recommend applying 30 to 50ml of product for each use. A bottle should last about one month (4-6 applications).

What should I apply in between the applications of Smooth Transformer?
The Smooth Transformer is designed to be used once a week.

Tests on the mask alone show 2x smoothness, 84% less frizz and 61% more nourishment***. We recommend using them in combination with the Smooth Transformer for optimal results.
Results of the Smooth Transformer
How long do the benefits of the Smooth Transformer last?
It ensures up to 2 weeks of smooth, frizz-controlled hair*.
What happens if I don’t leave Smooth Transformer on for 15 minutes?
The Smooth Transformer acts at the Keratin Alpha Level, where it reshapes the Keratin Alpha chains for long-lasting anti-frizz and smoothness. This is why the formula needs 15 minutes to act deep from within the hair fibres. If development time is less than 15 minutes, some remanence effect will be on the hair fibre, but performance peaks after 15 minutes of development time.
What happens if I leave Smooth Transformer on for longer than 15 minutes?
Performance peaks at 15 minutes of development time, there is no benefit to leaving it on for longer and we would recommend against this.
Will washing my hair more often reduce the treatment’s effect?
No, results are not washed away at your next shampoo. After the first usage, the product has an effect on the hair fibre to preserve smoothness and anti-frizz for up to 2 weeks*.
Will I notice visible changes after the first application, or only after completing all 4 weeks?
From the first application the product has an effect on the hair fibre, but performance peaks at 4 applications.

Why does the Smooth Transformer have a distinctive smell?
The Smooth Transformer is a unique hybrid that combines haircare with a texture treatment. The product is designed to reprogram Alpha Keratin chains for 2 weeks of smoothing and frizz control*, and for this reason it contains highly potent ingredients for the maximum efficacy, which may cause a distinctive smell. It is completely safe for use.
Is the Smooth Transfomer suitable for hair which has gone through a straightening treatment?
It is not recommended to use the Smooth Transformer in this instance as there could be risk of surface dryness due to the potency of the ingredients.

In addition, the shampoo, mask and serum can be used to preserve the results of your straightening treatment longer.
