The set consists of three products, each playing its own role in the same routine. You'll find them together in one of the most complete anti-frizz sets in our hair care range.

• Three products for one focused, daily routine
• Sulphate-free shampoo cleans gently without drying out
• Smooth Transformer works progressively: results build up
• Mask complements treatment days with smoothness and nourishment
• Suitable for all hair types, incluSief coloured hair
• Hair feels smoother without stiffness or heaviness
• Less styling time needed, even on normal wash days
• Based on keratin and amino acid chains for the hair fibre

The set works with a fixed schedule. The more strictly you follow it, the better your results after four weeks. Suitable for anyone with coarse, frizzy or hard-to-tame hair.

1. Wash your hair with the Keratin Alpha Sleek ProfesSional Shampoo 300 ml. Apply on wet hair, massage well and rinse thoroughly.
2. Use the Keratin Alpha Sleek Smooth Transformer 200 ml once a week after washing. Distribute through lengths and ends and leave on for 10 to 15 minutes. Rinse out afterwards.
3. Always blow-dry your hair after the Smooth Transformer. Heat activates the formula and enhances the smoothing effect.
4. On wash days without the Smooth Transformer, use the Keratin Alpha Sleek ProfesSional Masker 250 ml. Also leave this in for a few minutes before rinsing out.
5. Repeat this schedule for four weeks for the best result. According to L'Oréal ProfesSionnel, you peak after four applications of the Smooth Transformer.

Your hair becomes smoother week by week, frizz decreases and styling gets faster. This builds up because the Smooth Transformer contains a keratin-alpha shaper and amino acid chains that restructure the hair fibre on a keratin level, according to L'Oréal ProfesSionnel.

The sulphate-free shampoo prepares the hair without stressing the fibre, so the treatment penetrates better. After four weeks, the brand claims up to five times smoother hair, half the styling time and twice less frizz based on instrumental tests. These results apply to the full routine incluSief serum, but even with the three products in this set you’ll notice a clear difference. If you frequently choose L'Oréal ProfesSionnel, you know the brand always supports claims with test results.

According to L'Oréal ProfesSionnel, smoothness lasts up to two weeks after using the full routine. This is a brand claim based on instrumental and user tests.

In practice, this means your hair stays recognisably smoother and less frizzy between the two weekly Smooth Transformer applications. The mask on the other wash days helps support the effect. How consistently you follow the routine largely determines how long and strong the result lasts.

Yes, L'Oréal ProfesSionnel positions the line as suitable for all hair types, incluSief coloured hair. The sulphate-free shampoo is part of this: sulphate-free formulas are generally gentler on colour-treated hair.

If you have very fine or low-volume hair, it’s wise to limit the amount of Smooth Transformer. Fine hair users sometimes report intensely smoothing products can flatten hair. Start with a small amount and see how your hair responds.

The Smooth Transformer is the core of the routine: a weekly, progressive treatment with the strongest Smoothing effect. The mask is the nourishing addition for all other wash days.

You build up the Smooth Transformer over four weeks for maximum results and it needs heat to work optimally. The Keratin Alpha Sleek ProfesSional Masker 250 ml is a classic intense mask that provides smoothness and nourishment, but without the progressive protocol of the treatment. Together they keep your hair in good condition even between treatments.

The brand targets the line at all hair types, but the set works best for hair that is naturally thick, frizzy or hard to control. Think of hair that expands immediately in humidity, hair with lots of volume you want to keep in check, or hair that quickly bounces back to its own way after blow-drying.

For damaged hair that breaks easily or needs intense repair, the Absolut Repair Molecular Mask is a better match. That line focuses on hair reconstruction, while Keratin Alpha Sleek is about smoothness and frizz control. Curious if Keratin Alpha Sleek works for your curls? The line doesn't remove curl percentage and works progressively, so some curly hair users see more effect than others.
