Get answers to common questions about K18 treatment.

K18 is a peptide-based professional treatment that reconnects broken keratin chains, restoring strength and elasticity. Applied after chemical services, it penetrates the cortex to repair damage, reduce porosity, and prepare hair for safer color lifting and improved manageability.

Yes — we strongly recommend adding K18 for any highlight or bleach service, especially on overprocessed hair. It reinforces strands during lifting, reducing breakage and uneven lift. Follow-up home treatments are recommended for optimal, long-lasting repair.

We advise a minimum of five at-home K18 treatments to consolidate salon results. Used consecutively, they maintain molecular repair, improve texture, and extend protection between appointments for stronger, more resilient hair.

K18 significantly reduces additional damage by rebuilding internal bonds before or after lifting. While not a substitute for careful processing, it lowers breakage risk and improves hair resilience, especially on fragile or previously overprocessed strands.

Yes, K18 works on curly, straight, fine, and coarse hair by restoring keratin bonds. Individual results vary based on damage level; our stylists will assess and recommend frequency and at-home protocol for best outcomes.

A K18 salon application adds only about 5–10 minutes for application and a short activation time, fitting conveniently into most chemical services. Home treatments are quick and take under five minutes each for ongoing maintenance.
