K18 Leave-in Molecular Repair Hair Mask 5ml

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 + colour, chemical services and heat* – with immediate and lasting results to restore strength, softness, smoothness and bounce to hair.

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

Features:

• K18PEPTIDE™ is a biotech-developed peptide that mimics hair’s structure to reverse damage by reconnecting polypeptide chains and disulfide bonds broken during bleaching, colour 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, colour-safe, cruelty-free

How to use:

1. Shampoo, do not condition. Towel-dry thoroughly
2. 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
3. Let sit for 4 minutes. Do not rinse out
4. Comb, add product + style as usual. Use for 4-6 washes post-salon service, then as needed
