Kérastase Spécifique Bain Divalent is a luxury balancing shampoo formulated for hair with oily roots and dry or sensitized ends. The ultra-light formula purifies the scalp, regulates excess sebum production, and reduces scalp odors while gently cleansing without stripping moisture from the lengths. It is part of Kérastase's Spécifique scalp health collection, developed to restore harmony to hair affected by an unbalanced hydrolipidic film.

Clinically, the formula delivers a 61% increase in volume versus unwashed hair and 20% improved detangling compared to a non-conditioning shampoo. Key ingredients include Amino Acids, which balance the hair fiber and limit oxidation stress, and Vitamin B6 (Pyridoxine HCl), which shields hair from environmental aggressors. Salicylic Acid purifies the scalp at the surface level, while Capryloyl Glycine helps regulate sebum secretion. The result is soft, shiny hair with noticeable lift at the roots and smoothness through the ends.

To use, apply to wet hair and massage the lather thoroughly into the scalp and lengths before rinsing. For optimal results, repeat the cleansing step twice. The shampoo is suitable for daily use and has been tested under dermatological control. Each 8.5 fl oz bottle is salon-quality and provides substantial product even for longer or thicker hair.
