The Full Length Anti-breakage Hard Water Shampoo is the ultimate solution for hair affected by hard water. It detoxifies hair, removing stubborn buildup that causes dryness, dullness, and breakage without stripping away its natural moisture. Infused with activated charcoal, it works to clear impurities from the hair shaft while keeping it refreshed and nourished. The powerful formula features Klean Complex™, a blend of chelators that neutralises hard water minerals, preventing future damage and leaving hair soft, smooth, and resilient.

With the addition of 15 amino acids, the shampoo strengthens hair from within, restoring its natural shine and boosting thickness by 18% in just four weeks. Licorice Root hydrates and strengthens, while lactic acid exfoliates the scalp to reduce frizz and promote a healthier scalp environment. This shampoo is safe for all chemically treated hair, including colour-treated, keratin-treated, and Brazilian blowout hair. Enjoy hair that’s not only stronger and thicker but also free from the harsh effects of hard water.

Unlike typical shampoos that only wash away surface residue, the Full Length Anti-breakage Hard Water Shampoo delivers clinically proven results by actively improving hair thickness and strength from within. In a four-week clinical trial, participants who used the shampoo every other day experienced an average 17.71% increase in hair diameter, making strands visibly thicker and more resistant to breakage. The trial also revealed smoother hair texture in 7 out of 10 users, highlighting the shampoo’s ability to restore surface quality while protecting against the damaging effects of hard water.
