This shampoo restores volume and strength to fine, brittle, and thinning hair, preventing hair loss and damage, and increasing density and thickness. The sulfate-free formula repairs and strengthens hair from within the cortex (responsible for elasticity, strength, and color retention), hydrolyzed peptides provide an increase in volume for thin hair, and beta-hydroxy acids (BHA) exfoliate the scalp to reduce hair breakage and maintain optimal scalp condition without drying out the hair.
