The L'Oréal Alpha Sleek Keratin Mask is a professional hair treatment designed to smooth and nourish hair, reduce frizz, and improve manageability. This 500 ml keratin-enriched mask is suitable for various hair types, especially dry, damaged, or unruly hair. It works by depositing keratin proteins into the hair shaft, contributing to the repair and strengthening of strands while providing intense hydration. The creamy, rich texture allows for deep penetration, making hair feel softer, smoother, and more resilient after each use. Suitable for regular use in hair care, this mask can enhance the overall texture and appearance of hair, making styling and maintenance easier. It is free from parabens and sulfates, making it suitable for sensitive scalps or specific ingredient preferences. The product comes in a convenient, resealable container that ensures freshness and easy dispensing. For optimal results, apply to clean, towel-dried hair, leave on for 3-5 minutes, and then rinse thoroughly. This mask is a follow-up to previous keratin treatments from L'Oréal and offers an updated formula aimed at long-lasting smoothness and shine without weighing the hair down.
