K18 Professional Repair Hair Mist 150ml

K18: The Science of Hair Repair

K18 is a biotechnology haircare brand founded in the United States with one mission — to repair hair at a molecular level, not just mask the damage. Where most treatments coat the surface, K18 works from the inside out.

Their breakthrough is the K18Peptide™, a patented biomimetic peptide that reconnects broken keratin chains within the hair structure. The kind of damage that builds up over years of colour, bleach, heat and chemical treatments. Four minutes is all it takes for their Leave-In Molecular Repair Hair Mask to begin reversing that damage — no rinsing required.

K18 is particularly popular in professional salons, including our own here in Codsall, because the results are immediate and visible. Clients who've tried every bond-builder on the market often find K18 does what others promised. It's become one of the treatments we reach for most after colour appointments.

The range is intentionally small and focused — every product earns its place. Sulphate-free, silicone-free, and built around that core peptide technology. Whether it's the dry shampoo, the detox shampoo, or the mask itself, K18 products are designed to work with the repair process rather than interfere with it.

If your hair has taken a battering — and whose hasn't — K18 is worth trying properly.
