Full Length Anti-Breakage Hard Water Shampoo

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.

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.
