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

Rated 5 out of 5 by from The best I can honestly say this is the best bond building treatment I’ve ever used! It truly does protect and repair the hair. Personally, my hair had started breaking and wouldn’t grow past my shoulders since moving to my new home (which had horrible well water). I had a water filtration system and softener installed, but the K18 is what has brought my hair back to life; now it is noticeably thicker and way longer & healthy. I love it!

Rated 5 out of 5 by from Will blow your mind This treatment will blow your mind on how well it rebuilds the hair bonds. Make sure to not over use it and really work it in your hands until it turns thick and white.

Rated 5 out of 5 by from Weightless leave in repair Just a pump or two restores texture in waves and curls, conditions without weight and helps support fragile, processed hair. I really appreciate that it's not full of gunky silicone fillers like some other brands
