K18 Leave-In Molecular Repair Hair Mask 50ml
Why K18 Is Worth Every Penny
At £55, K18 is the most clinically advanced leave-in treatment we stock — and the results speak for themselves. Unlike traditional masks that coat the hair surface, K18's patented peptide technology works at a molecular level, reconnecting broken keratin chains inside the hair shaft to restore strength, softness, and elasticity from within.
What Makes It Different
- Patented K18PEPTIDE™ technology — clinically proven to reverse damage from bleach, colour, heat, and chemical treatments
- Works in just 4 minutes — no rinse required, no build-up
- One product replaces multiple treatments — deep conditioner, bond builder, and protein treatment in one
- Suitable for all hair types — including 4C, colour-treated, and chemically processed hair
How To Use
- Shampoo hair and rinse thoroughly (do not condition first)
- Towel dry to remove excess water
- Apply a small amount of K18 mask evenly through hair
- Leave for 4 minutes — do not rinse
- Style as usual
How Much Do You Need?
A little goes a long way. For short to medium hair, 1–2 pumps per session. For longer or thicker hair, 2–3 pumps. The 50ml jar typically lasts 8–12 applications.
Trusted by professional stylists worldwide. If you've tried everything else and your hair still isn't recovering — this is the one.
