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 so far, so good! One use on a client with severe sun it damage, and it made a drastic difference in breakage, porosity, elasticity, shine, & smoothness! She bought a 50ml to take home & we are excited to see what it does over the next 9 weeks!

Rated 5 out of 5 by from You see a difference after 1 use I really love using this before toning and after! 1-3 pumps only which is nice because I find I don’t run out of product too quickly which means more $ saved. You really notice a difference in their hair even after lighting!

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…

Rated 5 out of 5 by from K18 Saved My Hair K18 has saved my hair. I lighten and change my hair color pretty regularly and it has always left my hair very damaged. Ever since switching to K18 products my hair has grown longer and is so much softer than it had been in a very long time. I love how simple the system is and I recommend their products to anybody with damaged hair!

Rated 5 out of 5 by from It helped my hair grow I know it’s to improve the overall health of hair but because I’ve used it to repair my damaged hair, it’s grown significantly. It’s stronger, healthier, and shinier.

Rated 5 out of 5 by from Damaged, dry hair this is a life saver This helped my hair so much I was losing so much hair, due to bleach damage my hair was dry, brittle, falling so much I started seeing bald spots and this has helped saved my hair. I was starting to lose hope and K 18 changed my life. Better than anything (ola***x) was suppose to help but instead made my hair fall more and gave me bad dandruff this is amazing . I don’t ever do review but AMAZING

Rated 5 out of 5 by from Makes my hair soft! I got the smallest bottle to try out and I just ran out, it works so good my hair is so soft! I was a little skeptical because you’re not suppose to use conditioner with this but it definitely replaces the conditioner amazingly.

Rated 2 out of 5 by from Can’t get product out of bottle. Great product, but if you can’t get it out of the bottle, it does no good. They need to switch to a tube ASAP.
Date published: 2023-07-17
Rated 5 out of 5 by from Not your grandma's leave in! I was skeptical, leave-in repairing treatments can make the hair feel heavy and textured. This however, does not! The hair feels conditioned and ready for styling products as soon as they're up from the bowl. I'm sold

Rated 5 out of 5 by from 4 minute magic potion The K18 Molecular Repair Mask has totally revived my natural curl after going vivid. I use this every time I wash (I use the pH Maintenance Shampoo most often.) I also love it in the salon because it works like magic in literally 4 minutes.
Date published: 2023-07-01
Rated 5 out of 5 by from Hair saver I think the k18 molecular repair mask has been insurance for the hair on many lightening appointments. I like that it’s only one step and doesn’t need to be shampooed out. You may be weary at first not conditioning the hair or using products, but surprisingly all you need is the molecular repair mask on towel dried hair.

Rated 3 out of 5 by from K18 the PUMP does not work at all , I returned the first one because there was conditioner all on the outside of the bottle. the new bottle just dont pump AT ALL!!
