What It Is

Made to be used as part of the K18 PRO service (K18 PRO Mist + K18 PRO Mask)

 

This leave-in treatment mask does cleanup duty after damage caused during bleaching, chemical services, and heat. Powered by the K18PEPTIDE™ to reconnect broken polypeptide chains and disulfide bonds to renew strength and elasticity in just 4 minutes.

 

A retail-sized version of the K18 Mask helps to maintain your client's hair strength and elasticity in between salon appointments. This leave-in treatment mask for all hair types that reverses damage in 4 minutes. Patented peptide technology works to repair damage from bleach, color, chemical services & heat—restoring strength, softness, smoothness, and bounce to hair.

What It Does

• The K18PEPTIDE™ works at the innermost layer of hair, reconnecting polypeptide chains and disulfide bonds broken during bleaching, chemical services, and through heat damage. By addressing these damage sites at the innermost layer of hair, core strength and elasticity are renewed for strong, smooth, bouncy hair—even after the most extreme damage done in the salon.

• Damage is ongoing - Send the K18 retail sizes home with your client to keep hair health going, make services last longer, and maintain hair health in between appointments + the K18 PRO service.

What Else You Need to Know

• Powered by the patented K18PEPTIDE™, engineered over 10 years in a biotech lab to work on the molecular level to rebuild hair from the inside out in just 4 minutes.

• Because the K18PEPTIDE™ works at the molecular level, it works on every single hair type

• Clinically proven to reverse hair damage from: Bleach + Color, Chemical Services, Heat

• Restores strength, softness, smoothness, and bounce

• Immediate + progressive results

• Vegan, color-safe, cruelty-free

 

With just one salon treatment using the K18 PRO Service (PRO mist + PRO mask), hair is restored up to:

• 91% original strength*

• 94% original elasticity*

 

*Results observed in a clinical study while using mist and mask as part of a bleaching treatment. Results may vary depending on hair type, quality, and history.

Rated 5 out of 5 by from Brought my curls back to life Incredible product that brings my curls back to life. I use 2-3 pumps and warm it up between my palms, applying to damp hair. I wait a few mins then follow with any other styling products or hear styling. This is truly brought my curls back to life and made them so so soft again.

Rated 5 out of 5 by from K18 repair mask This product has blown me away!!! I had extremely damaged hair from over processing and not getting a regular haircut and continuing to over process my hair. I started using this as a sample, and I fell in absolute love with it, first try and I could brush my hair without feeling like I was ripping half of it out!!! I would recommend this to anyone who gets bleach regularly or anyone with untamable hair this is the best thing I have ever used!!!

Rated 5 out of 5 by from Best Bond Builder! This is hands-down, the best bond building product I’ve ever used especially when you use the whole line together. It really is amazing how much of a difference it makes in the hair texture and feel. The only problem I has is that now K18 the brand has an Amazon storefront and is now selling cheaper than what I can buy it on SalonCentric for.

Rated 5 out of 5 by from the GOAT hair treatment best innovation in the hair care world that i’ve experienced in the 42 years i’ve done hair. repairs quickly and easily -unfortunately like most product companies i think they will move away from selling professionally and market directly to our clients after we teach them how to use it and use our dollars to fund it… like most other great products…
