Restore hair's strength with the Pureology Strength Cure Dream Healer Serum, a lightweight leave-in hair serum that transforms damaged, colour-treated hair types. The formula is powered by a triple-action blend of lactic acid, citric acid and amino acids to detangle, visibly seal split ends* and improve the look of elasticity. Offering optimal results as part of the Strength Cure routine, the serum leaves hair with up to 72 hours of softness and shine. *When used with Strength Cure Shampoo, Conditioner & Serum, vs. non-conditioning shampoo.
