Why Choose Wigs & Warpaint for K18 Treatment in Sheffield
K18 is not a conditioning mask. It is a patented peptide treatment that repairs the internal keratin chains broken by colour, bleach and heat. Most treatments coat the surface. K18 fixes what's underneath. The bioactive peptide works inside the hair cortex, reconnecting broken polypeptide chains — the bonds that give hair its strength and elasticity. Hair doesn't just feel better. It actually is better. Stronger, more resilient, behaving like it did before the damage. We use K18 as a standalone treatment and alongside colour services. Four minutes added to your appointment. The results are cumulative — every treatment builds on the last. If your hair has been through repeated colour, bleach or heat styling, this is not optional. It is essential.
