Experience a revolutionary at-home leave-in treatment designed to repair even the most extreme hair damage and renew hair to its healthiest state. Powered by patented K18PEPTIDE™ technology, this innovative formula works on the molecular level to reconnect broken keratin chains in just 4 minutes. Clinically proven to reverse damage caused by bleach, color, chemical services, and heat*, it restores strength, softness, smoothness, elasticity, and bounce to all hair types and textures.

The lightweight cream formula detangles and softens without weighing hair down, helping transform dull, damaged hair into silky, smooth, radiant locks. Its pH-optimized formula (5.0–6.0) minimizes cuticle swelling, placing hair proteins in their most resilient state for lasting health and shine. A light floral fragrance features notes of jasmine and peony.

4-minute leave-in treatment to reverse hair damage

The K18PEPTIDE™ is engineered to reach the innermost layers of hair and reconnect polypeptide chains and disulfide bonds broken during chemical and heat treatments. This breakthrough technology delivers immediate and progressive results, reviving hair strength and elasticity while reducing frizz, breakage, and the appearance of split ends.

Suitable for fine, medium, and thick hair with straight, wavy, curly, or coily textures, this vegan, color-safe, cruelty-free treatment comes in recyclable packaging. For best results, shampoo and towel-dry hair thoroughly. Apply 1 pump, adding more as needed according to hair length, thickness, and condition. Work evenly through hair and leave in—no rinsing required.

In a clinical study on hair bleached 8 times, the biotech-powered K18PEPTIDE™ restored damaged hair by up to 82% after 2 uses. This product is an Allure Best of Beauty award winner and is recognized by CLEAN at Sephora for meeting standards beyond regulatory requirements while avoiding controversial ingredients.
