L'Oréal Professionnel Keratin Alpha Sleek Anti Frizz & Smoothing Treatment 200ml

L'Oréal Professionnel Keratin Alpha Sleek Anti Frizz & Smoothing Treatment 200ml is a professional at-home treatment designed to help tame unruly, frizz-prone hair. Powered by Keratin-Alpha shaper technology and amino acid chains, the creamy formula works to smooth the hair fibre, support volume control and enhance shine, while still respecting the integrity of the hair. Hair feels softer, looks more polished and appears more manageable, with results that may last for up to two weeks when used as part of the full Keratin Alpha Sleek routine.

Ideal for all hair types that struggle with frizz, excess volume or humidity, this treatment fits easily into a weekly haircare ritual after shampooing. The texture coats lengths and ends to help with detangling and to promote a sleeker, glossier finish once hair is dried and styled. Used regularly, it helps to reduce the time needed for daily styling and supports a smoother, more disciplined look between washes.

How to use
How to Use:
After shampooing, gently towel-dry hair. Shake the product well, then section the hair. Apply a generous amount evenly through lengths and ends, using more product for thicker or longer hair. Leave on for 10–15 minutes, then rinse thoroughly. For enhanced smoothing, dry hair completely and style with a hairdryer or straighteners.

Frequency:
Use once a week after shampoo, alternating with a nourishing mask on other wash days, or follow the usage guidance on the packaging.

Application Technique:
Work the formula through clean, damp hair from mid-lengths to ends, ensuring even coverage on each section. Comb through if needed to distribute the product before leaving it to act, then rinse well and style as desired.

Best Practices:
Apply only to freshly washed hair for best results. Adjust the amount according to hair length and thickness. Follow with a heat protectant or serum if desired, and style using gentle heat settings.

Safety Tips:
Avoid contact with eyes; if this occurs, rinse immediately with plenty of water. Use externally only and discontinue use if irritation occurs. Keep out of reach of children and always follow the instructions on the packaging.
