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

L'Oréal Professionnel Série Expert Keratin Alpha Sleek Serum is a daily leave-in hair serum developed to reduce frizz and unwanted volume while helping to reinforce the hair fibre. The formula is enriched with dimethicone and a 5% Keratin Sealer complex, which helps coat the hair surface and seal the hair’s keratin structure for a smoother, more polished finish. Heat-activated, it helps protect your hair against humidity (up to 80%*) and heat up to 230°C*. The lightweight, fast-absorbing texture distributes easily through mid-lengths and ends without weighing hair down, so your styling feels quicker and more controlled. The result is smoother-looking hair, less frizz and a visible, mirror-like shine.
