K18 Full Size Leave In Molecular Repair Hair Mask

Brand new! This is the full-size 1.7 fl oz leave-in hair mask. The K18PEPTIDE™ is clinically proven to repair damage on a molecular level from bleach + color, chemical services and heat – to restore strength, softness, smoothness and bounce to hair. The mask is pH-optimized (5.0-6.0) to help minimize cuticle swelling and put hair proteins in their most resilient state. It is also vegan, color-safe, and 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 damage - by working at the innermost layer of the hair, core strength and elasticity are renewed for strong, smooth, bouncy hair. •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.
