professional molecular repair mask

Takes damage repair further – biomimetic peptide seamlessly fits in and reconnects broken polypeptide chains at the molecular level. As a result, disulfide bonds are also reconnected for reinforced strength along the length + width of hair—offering comprehensive, lasting repair

Restores hair before and after color and chemical services 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

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 and with every service

Clinically proven to reverse hair damage – from: bleach* + color*, chemical services*, and heat*

The K18 professional molecular repair hair mask is meant to be used as the second part of the K18REPAIR™ service.

With a color or chemical service:

1. Before the service, apply K18 professional molecular repair hair mist. Wait 4 minutes. Do not rinse out.
2. Apply 1-3 pumps of K18 professional molecular repair hair mask based on your client’s length and density, starting at the ends and working up towards the roots. Let sit for 4 minutes. Do not rinse out.
3. Proceed with cut or style as usual.
4. If toning, use K18 PRO mist first, wait 4 minutes, then apply toner directly over PRO mist. Process as usual. Rinse or shampoo toner + apply K18 PRO mask per instructions above.

Without a chemical service:

1. Shampoo, do not condition. Towel-dry thoroughly
2. Apply 1-3 pumps of K18 professional molecular repair hair mask based on your client’s length and density, starting at the ends and working up towards the roots.
3. Let sit for 4 minutes. Do not rinse out.

• DO clarify before K18 if your client is a heavy product user (demineralize for mineral + metal buildup)
• DO apply on clean, damp hair (think about 65% wet)
• DO wait the full 4 minutes before combing or styling
• DO add whatever styling products you love after the 4 minutes

• DON'T use conditioner before applying K18 mask (you can apply after the 4 min but most find they don’t need it)
• DON'T overdo it—less is more
• DON'T rinse it out
