Hard water can do more damage than you think. With over 85% of U.S. households affected, mineral build-up from hard water is one of the leading causes of scalp irritation, dryness, and dullness. Designed as a weekly reset, the Act+Acre Clarifying Hard Water Scalp Treatment gently lifts away mineral build-up, product residue, and pollutants in just three minutes—without stripping the scalp or compromising hydration. Powered by 15% Vitamin C, this trichologist-developed formula breaks down stubborn mineral deposits that can cause brassiness and dullness, leaving your hair visibly brighter and softer after one use. 1% Betaine, a naturally derived amino acid, delivers deep hydration to improve elasticity and help prevent breakage, while 7% Inulin, a prebiotic derived from chicory root, rebalances the scalp microbiome to soothe irritation and promote a healthier scalp environment. The result: a scalp that feels clean and refreshed, and hair that looks shinier and smoother. In a 2-week independent consumer trial, 90% agreed the treatment removed mineral build-up and left hair feeling detoxed, and 85% agreed their strands looked more vibrant and less brassy. How to use: Wet scalp and hair thoroughly. Mix one sachet of powder with water to create a smooth paste. Apply evenly from scalp to ends and massage in. Leave on for 3 minutes, then rinse thoroughly. Follow with your Act+Acre shampoo and conditioner for best results. Ideal for all scalp types—dry, oily, or sensitive—and safe for most color-treated hair (perform a patch test before use on vibrant shades). Vegan and cruelty-free. Use weekly to reset your scalp and revive your shine. The detox that keeps your scalp balanced, your hair luminous, and your routine mineral-free. Weekly powder ritual clears hard water build-up and product residue with 15% Vitamin C. In a clinical study, 90% of participants agreed it removes hard water residue and mineral build-up.
