Full Cover Anti-Thinning Hard Water Shampoo

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.

Hello Klean, founded by Karlee Zhang and Omer Ozener, was born out of Karlee’s struggle with hair and skin issues caused by hard water during her travels. Determined to find a solution, she created Hello Klean to optimise water for healthier hair and skin. The brand’s mission is to offer effective beauty tools and body care products that counter the damaging effects of hard water. Every product is designed with specific ingredients to provide real results, free from harmful chemicals, and backed by clinical proof. Hello Klean is committed to sustainability, with vegan, cruelty-free, and eco-friendly packaging.
