Acidic grow full system density shampoo

Redken's Acidic Grow Full System thickening shampoo gently cleanses fine, flat, or fragile hair while rebalancing the scalp. Enriched with azelaic acid to maintain pH balance, caffeine to stimulate follicles, and prebiotics to moisturize, it strengthens the hair fiber and reduces breakage. Upon application, hair appears thicker, fuller, and stronger, even on color-treated hair.
