L'Oréal Professionnel Série Expert Keratin Alpha Sleek Professional Smoothing Treatment 200ml is an anti-frizz treatment that transforms hair for softness, controlled frizz, and instant shine.
L'Oréal Professionnel Série Expert Keratin Alpha Sleek Professional Smoothing Treatment 200ml is a professional anti-frizz hair treatment that transforms hair for greater softness, controlled frizz, and instant shine. Its formula contains a Keratin-Alpha Modeler and Amino Acid Chains, which work together to act on the hair at the level of alpha-keratin, smoothing the hair fiber while preserving its integrity. So, by acting on the structure of the fiber, this product helps control frizz and volume. The result is hair that looks and feels smoother, with lasting softness and visibly brighter shine after every use. Additionally, it also helps reduce styling time by half. Results last up to two weeks, and the formula works progressively, meaning continued use delivers increasingly better results over time.
Shake L'Oréal Professionnel Série Expert Keratin Alpha Sleek Professional Smoothing Treatment 200ml well before use. After shampooing, divide hair into two sections and apply evenly from mid-lengths to ends on each section, using 30 to 50 grams per application depending on hair thickness and length. Leave on for 10 to 15 minutes, then rinse. Use once a week, alternating with a mask on other wash days. Activate with heat and complete the routine with the Mirror Sleek serum. Best results are obtained after 4 weeks of use.
