Healthy hair grows from a healthy scalp — and this shampoo is built for exactly that. The Act Shampoo Extra is a clarifying, scalp-first formula that removes buildup, balances sebum, and delivers active hydration to both the scalp and hair in one wash. Hydrolyzed amaranth protein repairs and fortifies the hair structure, while hyaluronic acid and urea hydrate the scalp at a cellular level. Lactic acid gently exfoliates dead skin cells and balances pH, and extracts of black willow bark, black truffle, and melon soothe, nourish, and protect. With coconut and broccoli oils for deep conditioning and a prebiotic ferment complex to support scalp microbiome health, this is the shampoo for those dealing with buildup, dryness, hair loss, or a scalp that simply doesn't feel balanced. Suitable for all hair types including colour-treated, fine, and curly. Also available in 1000ml.
