The K18 PEPTIDE leave-in molecular repair mask, a haircare breakthrough that delivers transformative results in just 4 minutes. Powered by a clinically proven biotech-developed peptide, K18PEPTIDE is engineered to reverse hair damage caused by bleaching, colouring, chemical treatments, and heat, providing both immediate and long-lasting benefits. This innovative formula works at the molecular level, reconnecting polypeptide chains and disulfide bonds that are often compromised during various hair treatments. Suitable for all hair types, this vegan and colour-safe treatment is designed for ease of use, with detangling and softening properties.

How to Use:

1. Shampoo your hair (do not condition) and towel-dry thoroughly.

2. Apply 1-3 pumps of K18 leave-in molecular repair hair mask, starting from the ends and working towards the roots.

3. Allow it to sit for 4 minutes without rinsing.

4. After 4 minutes, comb your hair and style as usual.

5. Use for 4-6 washes after a salon service and as needed.

Dos and Don'ts: 

DO clarify your hair before using K18 if you regularly use heavy hair products to remove mineral and metal buildup.

DO apply the product to clean, damp hair. 

DO wait the full 4 minutes before combing or styling.

DO follow up with your preferred styling products after the 4 minutes.

DO use the treatment for 4-6 consecutive shampoos for progressive results. 

DON'T use conditioner before applying the K18 Mask (you can apply it after the 4 minutes, but many find it unnecessary).

DON'T overuse the product; a little goes a long way.

DON'T rinse it out. Experience the future of hair repair with K18PEPTIDE™ and unveil hair that is stronger, smoother, and full of life.
