Full Cover Anti-Thinning Hard Water Shampoo delivers a powerful solution for thinning hair caused by hard water. Its unique formula neutralises hard water minerals, heavy metals, and chlorine, effectively preventing follicle clogging and promoting healthy hair growth. The shampoo strengthens hair from the roots, reduces hair fall by 19% in just three months, and restores natural fullness to hair.

Key ingredients include Aminexil, which enhances scalp circulation to create a solid foundation for thicker hair, and Biotin, which boosts keratin production to improve hair resilience. Astaxanthin shields hair follicles from oxidative stress, keeping hair healthier and more vibrant. The proprietary Klean Complex neutralises stubborn minerals like calcium and magnesium, preventing them from clinging to hair and ensuring it remains smooth and full.

With Full Cover Anti-Thinning Hard Water Shampoo, hair feels cleaner, stronger, and visibly fuller. Clinically tested and safe for all chemically treated hair, including colour, keratin, and Brazilian blowouts, this formula fits seamlessly into any haircare routine.

Full Cover Anti-Thinning Hard Water Shampoo stands out with clinically proven results that go beyond basic cleansing. In a study involving 23 participants over 84 days, consistent use led to a 20% reduction in hair loss and a 13.73% increase in local hair density. While most shampoos focus on surface-level results, this formula tackles mineral build-up from hard water, strengthens hair at the root, and promotes healthier growth. Backed by real data, it delivers visible improvements in fullness and thickness with continued use.
