Full Control Anti-Thinning Scalp Serum is a lightweight treatment created to help protect the scalp from water damage and mineral buildup while supporting stronger-looking hair from the root. Designed for daily use, it helps reduce shedding over time and promotes a healthier scalp environment.

Klean Complex™ works to counteract mineral buildup and support balanced scalp pH, while improved hydration helps calm visible signs of inflammation and rebalance the scalp microbiome. The fast-absorbing formula penetrates effectively during the post-wash window, helping protect the scalp for up to 72 hours without leaving residue.

Dual chamber technology keeps key actives separate until first press, helping preserve potency and pH stability for consistent performance. With regular use, hair appears stronger, fuller and better supported at the root.

Full Control Anti-Thinning Scalp Serum uses dual-chamber technology to protect ingredient stability and potency until first use. Rather than combining all actives into a single formula where peptides and antioxidants can degrade or shift outside their optimal pH range, the system keeps the active blend and hydrating base separate to prevent oxidation and instability. Once activated, the formula mixes freshly to deliver maximum performance. It features peptide growth factors to support renewal pathways linked to healthy-looking hair density, 0.4% zinc chloride to enhance peptide delivery and maintain a balanced follicle environment, and 5% green tea extract to provide antioxidant support and calm visible sensitivity. Klean Complex™ works alongside osmolytes such as erythritol, trehalose and betaine to help counteract hard water minerals, support scalp pH balance and reinforce hydration. The formula excludes over 1,600 concerning ingredients, including SLS, SLES, parabens, phthalates and silicones. This advanced system helps you support fuller-looking, healthier hair from the root.
