K18 Leave-In Molecular Repair Hair Mask 

Using the K18 Mask at Home

The only patented bioactive peptide treatment clinically proven to repair and reverse damage caused by chemical treatments, heat styling, and mechanical styling.

1. Shampoo your hair; do not use conditioner. Towel-dry thoroughly.

2. Start with one pump of the K18 Mask and add more as needed, depending on the length, thickness, and condition of your hair. Use the mask sparingly, though—a small amount goes a long way. Work it evenly into your hair, one pump at a time, from the ends to the roots.

3. Leave the mask on for 4 minutes to activate it.

4. DO NOT rinse out.

5. Style as usual.

NOTE: If the client uses heavy products such as oils, silicones, and film-forming agents, a detox shampoo beforehand ensures the best results. Product buildup can act as a barrier, so a deep cleanse may be necessary. K18 can also be used as a standalone at-home treatment without having undergone a salon treatment or services using K18.
