Discover K18 — The Ultimate Hair Treatment
K18 isn't a mask — it's a peptide treatment that rebuilds broken bonds inside the hair shaft. Here's what it actually does.
K18 has become one of our favorite in-salon and at-home treatments for good reason. Here's what it actually does.
What K18 is
A patented bioactive peptide that penetrates the hair shaft and reconnects broken keratin chains from the inside.
Salon use
We apply K18 during and after chemical services — lightener, color correction, extension installs — to preserve strength.
Home use
The K18 leave-in mist is a 4-minute treatment applied to damp hair 1–2× per week. No rinsing required.
When to use it
After any chemical service, weekly for extension clients, and any time your ends feel brittle.
