Smoothness you can feel. The L’Oréal Professionnel Keratin Alpha Sleek Professional Hair Mask is a rich, sensorial treatment formulated with Keratin Sleeker and amino-acid chains. It nourishes as it reshapes and smooths the hair’s keratin, so frizz-prone lengths dry softer, sleeker and shinier.
It is the maintenance step of the Keratin Alpha Sleek routine: on the wash days you are not using Smooth Transformer, the mask keeps the smoothing going between salon visits and gives an instantly smoother result after shampoo.
Who It’s Best For
Frizz-prone, unruly hair and hair that reacts to humidity.
Natural, colour-treated and chemically treated hair.
Key Benefits
Nourishes and hydrates: Rich, creamy care that softens the fibre without weighing it down.
Reshapes keratin: Smooths the hair’s keratin to control frizz and volume.
Instant shine: Leaves lengths glossy from the first use.
Clean formula: Free of artificial colourants and alcohol.
Usage
After shampooing, apply evenly from mid-lengths to ends. Leave on for 5 minutes, then rinse thoroughly and dry and style as usual.
Use it on the wash days you are not using Smooth Transformer, and alternate the two week to week to keep the smoothing going.
