L'Oreal Professionnel Keratin Alpha Sleek

Meet Keratin Alpha Sleek, L'Oreal Professionnel's most advanced smoothing range, formulated to transform hair at the deepest level of the fibre. Unlike surface-level smoothing treatments, Keratin Alpha Sleek works at the Keratin Alpha level - the primary structural protein at the very core of each strand - to reprogram hair shape, control frizz and volume, and deliver up to two weeks of smooth, sleek results with just four applications of the full routine. The range includes a sulphate-free Shampoo, Smooth Transformer treatment, nourishing Mask and Mirror Sleek Serum, working in sequence to cleanse, smooth, hydrate and seal. The result is five times smoother hair, two times less frizz, and daily styling time cut in half. Suitable for all hair types.
