Why you need it
L'Oréal Professionnel Keratin Alpha Sleek Hair Mask keeps frizz under control between your Alpha Sleek Transformer treatments while delivering deep nourishment where your hair needs it most. This professional Keratin hair mask works by smoothing the hair fibre and supporting keratin structure, helping reduce puffiness, tame volume and keep hair looking sleek for longer. The rich, conditioning mask coats the hair to soften and hydrate without weighing it down, making it ideal for frizzy, dry or hard to manage hair. Keratin Alpha Shaper and amino acid chains help reinforce the fibre while improving shine and manageability, so hair feels smoother and looks frizz free after every use. Used alongside the shampoo and smoothing treatment, this professional hair mask helps lock in that just styled, frizz free finish, keeping hair soft, glossy and sleek for up to 2 weeks.
For best results, alternate with the Smooth Transformer once a week.
