• Up to 84% less frizz after using the mask
• Suitable for coloured hair
• No artificial colours or alcohol in the shampoo
• Hair feels softer and is easier to comb
• Shinier hair after the very first wash

You use the four products alternately, depending on your wash day. This way you get the most from the L'Oréal ProfesSionnel Keratin Alpha Sleek Complete Set - 300+250+200+50ml.

1. Wash your hair with the Keratin Alpha Sleek Shampoo (300 ml). Work a generous amount through your wet hair, massage well and then rinse out.
2. Next, choose: if you use the Smooth Transformer, skip the mask. If not, go to step 3.
3. Apply the Keratin Alpha Sleek Mask (250 ml) to the lengths and ends of your hair. Leave on for five minutes and rinse well.
4. Want a more intense treatment? Use the Keratin Alpha Sleek Smooth Transformer (150 ml) once a week after washing. Leave in and rinse out.
5. Finish with the Keratin Alpha Sleek Conditioner (300 ml) for daily detangling and light hydration.
6. Dry and style your hair as usual.

Do you also have curly hair you prefer to style? The Curl ExpresSion Cream In Jelly Definition Activator is a great addition if some days you want to emphasise your curls instead of smoothing them.

Your hair becomes smoother because the formula works on the keratin structure inside the hair fibre. Amino acid chains fill small damages and smooth the outer hair. You notice this in less frizz, more shine and hair that’s easier to style. Glycerine in the mask also helps your hair retain moisture, keeping it soft all day. The result is frizz control that lasts beyond several washes. This makes the set a full professional hair treatment at home. With the right routine, you get the best results.

Yes, the Keratin Alpha Sleek Shampoo has no sulphates, artificial colours or alcohol. It gently but thoroughly cleanses your hair, without drying or damaging it. This is great if you have coloured hair, as your colour stays beautiful and intense longer.

With regular use of the full routine, the smooth effect lasts up to two weeks. Exactly how long depends on how often you wash your hair and how naturally frizzy it is. Use the Smooth Transformer weekly and shampoo and conditioner with every wash? Then you’ll notice the result lasts longer over time.

The mask and the Smooth Transformer are similar but serve different purposes. The L'Oréal ProfesSionnel Keratin Alpha Sleek Mask is a nourishing mask you use regularly for hydration, softness and less frizz. The Smooth Transformer is a weekly treatment that penetrates deeper and keeps your hair smooth longer. Use the L'Oréal ProfesSionnel Keratin Alpha Sleek Mask on days you don’t use the Smooth Transformer.

The L'Oréal ProfesSionnel Keratin Alpha Sleek Complete Set - 300+250+200+50ml is the best choice if your hair is frizzy, hard to style or quickly gains volume from moisture in the air. The set works well for thick, curly, stubborn and coloured hair. Want to keep your curls and just add more definition? Then check the Curl ExpresSion Caring Water Reviving Spray. If your hair is seriously damaged from bleaching or perManenting and needs repair, the Absolut Repair Molecular Set is a better choice, as it focuses on rebuilding hair structure. The Keratin Alpha Sleek set is made for those who prioritise smoothness and frizz control.
