The Full Length Anti-Breakage Shampoo is specifically designed to combat the damaging effects of hard water. It works by neutralising harsh minerals like calcium and magnesium, which can cling to your hair and cause dryness, breakage, and a rough texture.

Our unique Klean Complex™ is at the heart of this formula, actively binding to these minerals and heavy metals, preventing them from accumulating on your strands.

With consistent use, you'll notice stronger, more manageable hair that’s protected from the daily wear and tear caused by mineral buildup.

Our Full Length Anti-Breakage Shampoo was put to the test in a clinical trial designed to measure its effectiveness in improving hair thickness and reducing breakage, especially for those affected by hard water. The trial involved 10 participants who were instructed to use the shampoo every other day for four weeks.

The study began with baseline measurements of carious hair types, hair thickness and condition. Over the course of the trial, participants' hair was regularly assessed to track changes in thickness and surface quality. By the end of the four-week period, the shampoo had increased hair diameter by an average of 17.71%, making hair visibly thicker and more resilient against breakage. Additionally, improvements in hair surface were observed in 7 out of 10 participants, indicating a smoother appearance.
