L'Oréal Professional Série Expert Keratin Alpha Sleek Serum 50 ml

L'Oréal Professionnel Série Expert Keratin Alpha Sleek Mirror Sleek Serum is a daily leave-in hair serum specially developed to reduce frizz and unwanted volume while reinforcing the hair fibre. This leave-in serum is enriched with a targeted blend of dimethicone, Keratin Sleeker and amino-acid chains. Together, these powerful ingredients create a protective shield on the hair’s surface and work at the keratin level to help reprogramme the hair structure, leaving your hair smoother for longer with a silky finish. It helps seal the hair structure and visibly smooth the look of split ends, supporting a more polished, mirror-like shine. With daily use, your hair is better protected against humidity (up to 80%*) and heat up to 230°C*. The lightweight, fast-absorbing serum texture spreads easily through lengths and ends without weighing hair down. The result is smoother hair, less frizz and enhanced shine.
