Hello Klean Anti-Breakage Shampoo - Repair Damage Caused by Hard Water for Thicker & Healthier Hair - Deeply Cleansing & Non-Stripping - Lifts Dirt, Oil, Minerals, Heavy Metals & Chlorine Residue

Hello Klean
Why we love it
  • Neutralizes harsh water minerals.
  • Strengthens and hydrates hair.
  • Safe for all hair types.
Main Highlights
  • IT'S NOT YOU, IT'S YOUR WATER: Heavy metals, unwanted minerals and chlorine are very commonly found in hard water. Washing your hair in this type of water can lead to mineral build-up which leaves your strands feeling dry and rough. It can also lead to magnesium build-up which blocks the strands from being able to absorb moisture, resulting in brittle hair which is prone to breakage.
  • AWARD WINNING FORMULA FOR STRONGER HAIR: Our Full Length Anti-Breakage Shampoo neutralises harsh hard water minerals, prevents breakage, and restores strength, hydration, and pH balance for healthier, more resilient hair. That's why it won the Best Repairing Shampoo Award in the Cosmopolitan Summer Beauty Awards!
  • UNIQUE FORMULATION: Our specially selected ingredients clean hair whilst leaving it stronger and healthier. Activated charcoal removes build-up and detoxifies by absorbing impurities. Licorice root strengthens and hydrates, transforming hair from dull to shiny. Lactic acid gently exfoliates the scalp, reducing frizz. Our Klean Complex neutralises minerals, chlorine, heavy metals and pollutants in your water - balancing your hair's pH, removing build-up and leaving hair soft and smooth.
  • SUITABLE FOR ALL HAIR TYPES: Our formula has a unique texture which transforms from a charcoal gel to a bouncy white foam which is soft and non-stripping on your hair. The pH balanced formula is gentle on your strands, making it safe for coloured and chemically treated hair.
  • HOW TO USE: Twist the cap counter clockwise to open and pump into the palm of your hand. Apply the shampoo to your head and massage into a rich lather. Make sure to massage into the root of your hair as well as your scalp. When finished, make sure to rinse thoroughly. For the best results, follow up with the Hello Klean Anti-Fading Conditioner. Smells like a splash of bergamot and lavender.
