Undo Hair Damage in Just 4 Minutes—For Good

We’ve all been there—fried, brittle, lifeless hair from years of heat styling, bleaching, and coloring. Deep conditioners only mask the damage. Protein treatments take forever and leave buildup. Salon visits? Expensive and time-consuming.


That’s where K18 Leave-In Repair Hair Mask changes everything.


Powered by K18PEPTIDE™, a biotech breakthrough, this leave-in treatment doesn’t just coat your hair—it permanently reverses damage at the molecular level. In just 4 minutes, K18 reconnects broken keratin chains, restoring hair strength, elasticity, and shine as if the damage never happened.

📦 You've unlocked free shipping!

K18PEPTIDE™ is a biotech-developed peptide that mimics hair's structure to reverse damage by reconnecting polypeptide chains and disulfide bonds broken during bleaching, color and chemical services + heat*.


pH-optimized (5.0-6.0) to help minimize cuticle swelling + put hair proteins in their most resilient state


Cream format enables easy, lightweight application across all hair types, with detangling and softening benefits


Vegan, color-safe, cruelty-free

I love it! 😍

I’m a hairdresser and never heard of this. I decided to treat myself and go to a salon to get my hair done. I’ve used Pravana Wild Orchid for years and it always fades out in about 2-3 weeks with only washing my hair 1-2 times a week. The hairdresser used this treatment and I am in love!! I’m going on almost 5 weeks and my hair hasn’t faded a bit!! It’s healthier looking and I don’t need as much conditioner either!! I strongly recommend this!!
