K18 Biomimetic Hairscience Leave-In Molecular Repair Hair Mask (150ml) is a leave-in molecular repair hair mask which reverses damage caused by colour and bleach, chemical processing, heat, and mechanical styling. Formulated using bio-active peptide, this treatment increases overall strength and improves elasticity in all hair types, resulting in reduced breakage, split ends, and colour fade.

 

The mask has a lightweight, moisturising effect which detangles and keeps the hair smooth and soft without weighing it down. For best results, use for the first 4-6 consecutive washes following a service, and then every 3-4 washes as needed to maintain hair strength.

 

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 colour 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*

 

Cruelty-free & vegan-friendly.

 

Made to be used as part of the K18REPAIR™ service (K18 PRO mist + K18 PRO mask)

This leave-in treatment mask repairs hair damage and restores hair to a healthy state after salon services. Powered by the K18PEPTIDE™ to reconnect broken polypeptide chains and disulfide bonds to renew strength and elasticity in just 4 minutes. This mask is clinically proven to repair damage from bleach + colour, chemical services, and heat for immediate + lasting results.

 

Cream-based format helps soften, smooth, and condition hair.
How to use

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

With a colour or chemical service:

  • Before the service, apply K18 professional molecular repair hair mist. Wait 4 minutes. Do not rinse out.
  • 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.
  • Proceed with cut or style as usual.
  • 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:

  • Shampoo, do not condition. Towel-dry thoroughly
  • 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.
  • Proceed with cut or style as usual.
Key benefits
  • K18PEPTIDE™ is a biotech-developed peptide that mimics hair's structure to reverse damage by reconnecting polypeptide chains and disulfide bonds broken during bleach, colour, and chemical services, and heat*.
  • pH-optimized (5.0-6.0) to help minimise cuticle swelling + put hair proteins in their most resilient state after salon service or shampoo
  • Cream format enables easy, lightweight application across all hair types, with detangling and softening benefits.
  • Vegan, colour-safe, cruelty-free

✅ DO clarify before K18 if your client is a heavy product user (demineralise 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
