SKINCHEMISTS Biotin Hair Growth & Thickening Shampoo is a 250ml formula designed for thinning, weak, and lifeless hair. Enriched with biotin, taurine, and lysine HCl, it supports healthier hair growth and improves density from root to tip. The shampoo deeply cleanses the scalp without stripping natural moisture, leaving hair feeling thicker, smoother, and more manageable. It also contains panthenol, allantoin, and conditioning agents to strengthen strands and enhance resilience. Free from parabens and sulfates, this cruelty-free product helps revitalize hair appearance over time. Use regularly by massaging into the scalp and rinsing thoroughly.
