Keratin is the SINERGY COSMETICS line designed for hair that is brittle, fragile, or stressed by chemical treatments and heat tools. The collection includes two care products to use after washing: a repairing serum and a bi-phase treatment.
Keratin B-Phase Y 4.4 is practical to spray onto towel-dried lengths: shake well to mix the two phases and comb through without rinsing. Kerargan Repair Serum Y 4.3, on the other hand, is ideal for the ends; apply a small amount before blow-drying or on dry hair as a finishing touch. Used together, they allow you to build a simple routine for softer and more manageable lengths. For more tips, read our guide to damaged hair.
