Description
A leave-in treatment mask that works on the molecular level to reverse hair damage in just 4 minutes. The K18PEPTIDE is clinically proven to repair damage from bleach + color, chemical services and heat* – with immediate and lasting results to restore strength, softness, smoothness and bounce to hair.
- 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
BENEFITS
Takes damage repair further – reconnects both polypeptide chains (and as a result, also reconnects disulfide bonds) for strength along the length + width of the hair - offering comprehensive, lasting damage repair
Restores hair from even extreme damage - by working at the innermost layer of the hair, core strength and elasticity are renewed for strong, smooth, bouncy hair
Delivers immediate and lasting results – hair is repaired from the first use and lasts past your next wash, for ongoing reparative benefits
Simplified repair - convenient, leave-in formula works in just 4 minutes, with no extra rinse required
Works on all hair types – because K18PEPTIDE™ works on a molecular level (where all hair is the same), this product is effective on all hair types
HOW TO USE
- Shampoo, do not condition. Towel-dry thoroughly
- Apply 1-3 pumps of K18 leave-in molecular repair hair mask based on your length and density, starting at the ends and working up towards the roots
- Let sit for 4 minutes. Do not rinse out
- Comb, add product + style as usual. Use for 4-6 washes post-salon service, then as needed
DOS AND DONT'S
- DO clarify before K18 if you’re a heavy product user (demineralize for mineral + metal buildup)
- DO apply on clean, damp hair
- DO wait the full 4 minutes before combing or styling
- DO add whatever styling products you love after the 4 minutes
- DO use for 4-6 shampoos consecutively for progressive results
- DON'T use conditioner before applying K18 Mask (you can apply after the 4 min but most find they don’t need it)
- DON'T overdo it—less is more
- DON'T rinse it out
