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 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.

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.

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!!

Rated 5 out of 5 by from Patience is the key I purchased k18 for breakage and dryness due to harsh bleaching, at first I was disappointed because my hair didn’t seen better or any different but I decided to stick to the recommended 4-6 wash application and after the third use my hair was miraculously improved. Give it time and trust the princess. I use the L’anza keratin healing shampoo to wash my hair then k18 and after the 4 minutes I use the L’anza keratin healing smoother and the healing oil combo for a smooth and shiny blowout. My hair is bouncy, healthy and full of body. I absolutely love my hair routine.

Rated 2 out of 5 by from Wouldn't spend the money...again As other reviewers have said, the pump is terrible. I now have a half-empty bottle with product that is no longer accessible and the top doesn't come off. As for the product...MEH...At the price point, I expected a whole lot more.

Rated 5 out of 5 by from REVIVED I actually love this! It makes the most damaged and dried out hair from lighting feel so soft

Rated 5 out of 5 by from Love it. A little goes a long way. I got a sample and it doesn't take much. I have bleached, bleached, bleached and toned my hair so I can go with my natural gray. My hair had been processed to within an inch of it's life and even the first time I used this I could see a difference in the texture and the way it took to styling. Love it.

Rated 5 out of 5 by from Follow Instruc. & voila! Repaired healthier hair Wow. I really love this product. Despite some of the reviews, I bought it, and boy am I glad I did! Works great with chemically treated hair. Follow instructions and voila! You got repaired, healthier hair!

Rated 5 out of 5 by from This truly is a miracle This product is incredible. This was used in my hair right after processing. My hair is baby fine with a very slight wave. This makes my hair super thick, looking and wavy. I highly recommend this product.

Rated 5 out of 5 by from My hair looks and feels so much better! I've seen this product being raved about all over social media, and then I saw a couple dermatologists who also recommended it. So I placed an order and have used it two days (supposed to use 4-6 shampoos, then as needed) My baby fine, thinner dry, frizzy, menopause hair looks and feels so good! Better than anything I have tried, to be honest. It did not weigh my hair down at all, which I was surprised cause other people said it did to theirs or clients. I just recommended it to a girlfriend and I would highly recommend it to anyone who has damaged hair.

Rated 2 out of 5 by from Meh... I'm so back and forth on this product. On a few clients it works really well, stronger smoother hair almost instantly. In others, it is a disaster. I've had clients where it destroyed their curl pattern. In clients with thin, fine hair, it frequently weighs it down so much they think they are losing hair. Just don't love it.

Rated 1 out of 5 by from Not happy I recently had my hair bleached and I bought into all the hype with this product. My hair looks TERRIBLE. It looks and feels like hay. I seriously don't want to go out in public with hair that looks this bad. I am searching for another product.

Rated 5 out of 5 by from Best hair repair I've used this 5 times on myself and I was already impressed after only the first use! My only issue is I wish I had ordered it sooner.

Rated 5 out of 5 by from New product for damaged hair. This is an amazing product, it protects hair from heat and bleach damage in only 4 minutes. I recommend it, it’s a great product.

Rated 1 out of 5 by from Would not recommend K-18 Hair Mask or K-18 Company I ordered the K18 hair mask online from Salon Centric because my closest store is 25 minutes away. When I got it, it looked as if it leaked out of the bottle. It wasn’t a big deal, I just wiped the bottle off but when I went to use it, it would not pump. It barely would spit out bits of product here and there. I drove up to the store to return it and replace it. Easy exchange. Except when I got home, the new mask I got did the same thing. I pumped it over a hundred times with nothing coming out. So yet again, I drove back up to the store and did another exchange. I checked this time in the store and after the 3rd pump, the product came out nicely. I was satisfied. I came home, washed my hair, used the mask. Everything was good. Two days later, I go to repeat the same process and now the pump isn’t working again! I don’t know why but this is the third one I’m having problems with. The pump does not work. I even contacted K-18 company directly. After telling me about to poke the hole in the bottom of the container (which I had already tried with no success) they told me to just take it back for a forth exchange…… I ended up just prying the top off and using it that way. I’ve only used the product a few times since it’s been such a hassle to get it out of the bottle. So far it seems to leave my hair heavy and greasy even using a less amount each time resulting in having to wash my hair more frequently. I don’t see the hype in it and frankly, I am not satisfied with the company’s response to my inconveniences of their product malfunction. I don’t believe it’s worth recommending.

Rated 1 out of 5 by from Wish I could try it but the pump isn’t working I was excited to use it but when I received it the pump is malfunctioned. I keep pumping it and no product comes out. Very disappointed.

Rated 5 out of 5 by from don’t walk, run! This line is simply amazing. I’ve never worked with anything quite like it. We had some samples in my salon and the few times I tried it I fell in love. My clients hair was velvety soft and visibly stronger. But the whole line and make sure every client leaves with something from it
