More to know

• 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.

Key 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.
