What It Is

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

• This leave-in, lightweight mist repairs existing damage to strengthen hair’s defenses and make it more resilient prior to salon services.

• This PRO-exclusive product helps services apply and perform better, leaves hair healthier, and color lasts longer. Works in just 4 minutes in a convenient spray-on format.

What It Does

• 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.
• Renews hair for better in-salon results - restores chemically damaged hair and makes hair more resilient for optimal salon transformations. Use before services for a stronger foundation and to help prevent damage during services.
• Resets hair’s strength and elasticity – allowing you to push transformations further with confidence.
• 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.

What Else You Need to Know

• In cases of extreme damage or certain salon services, the mist works alone to renew hair without weighing it down.

• 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.

• pH level 7.5-8.0 makes the treatment more efficient by swelling the hair’s cuticle, allowing the K18PEPTIDE™ to better access the core.
• Made without emollients, the PRO mist won’t interfere with chemical and color services.

• 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.

How to use with a chemical service:

1. Turn trigger to “on” position. Section dry hair into 4 quadrants.
2. Apply 6-10 sprays of K18 pro chelating hair complex per quadrant*.
3. Wait 4 minutes after chelating** (do not rinse out), then apply a minimum of 10 full sprays of K18 professional molecular repair hair mist to each quadrant, increasing up to 20 sprays per quadrant as needed, depending on client’s length, density, and level of damage.
4. Wait 4 minutes (do not rinse out).
5. If needed, dry the hair prior to applying lightener or color. Then perform your desired technique.
6. Process your lightener or color as usual, then rinse and shampoo with K18 PEPTIDE PREP™ detox shampoo. Do not condition.
7. Follow with the K18 professional molecular repair hair mask as directed to complete the molecular repair service

 

How to use as part of a styling service or as part of a K18 molecular repair service standalone treatment:

1. Section dry hair into 4 quadrants.
2. Apply 6-10 sprays of K18 pro chelating hair complex per quadrant*.
3. Wait 4 minutes after chelating**, then rinse and shampoo with K18 PEPTIDE PREP™ detox shampoo. Do not condition.
4. Towel dry hair, then apply a minimum of 10 full sprays of K18 professional molecular repair hair mist to each quadrant, increasing up to 20 sprays per quadrant as needed, depending on client’s length, density, and level of damage.
5. Wait 4 minutes, then 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.
6. Wait 4 minutes, then apply 1-3 drops of K18 molecular repair hair oil to mid-lengths and ends.
7. Wait 4 minutes, then style as usual.
8. Add an additional 1-3 drops of K18 molecular repair hair oil to dry hair as a finisher.
*For cases of extreme metal + mineral buildup, process up to 10 minutes, then proceed with the instructions.

Rated 5 out of 5 by from best. repair. mist. ever. Not only do I use this after I get out of the shower, but I even use this when I go to bed at night when I put my hair in braids, I use it when the ends are a little dry in between washes, it’s not heavy, it’s light enough to put on dry hair and it doesn’t dry oily, and it’s not heavy either. It’s simply the best. This regimen has changed my hairs life.

Rated 1 out of 5 by from Item never received NEVER RECEIVED MY ITEM. Called Salon Centric to advise they sent me chelating spray instead and she assured me I’d get the product and an update email on what to do with wrong product received but haven’t gotten either! Frustrating because I’m visiting my daughter and was trying to do her hair

Rated 3 out of 5 by from Im in the middle with this product. I took the certification online to make I use it properly. I don't really like this product as much as Olaplex even though it goes deeper and rebonds more. It left a scratchy dry and gummy feeling on the ends of the hair when dried and felt great, soft and strong when wet. I made sure to not use this in error so perhaps Im actually feeling the new synth bonds on the hair ends when its dry. I also used the complete system a few times to see maybe over time results and its the same.

Rated 5 out of 5 by from Worth every penny As a hairstylist with years of experience, I’ve always been on the lookout for products that deliver exceptional results for my clients. The K18 Pro Mist Professional Molecular Repair Hair Mist is hands down one of the best I’ve ever used! This product works at the molecular level to repair and strengthen hair, and the results are nothing short of miraculous. After just one treatment, I noticed a significant reduction in breakage and split ends. My clients’ hair feels incredibly soft and looks stunningly shiny and healthy. One of the things I love most about K18 Pro Mist is its lightweight formula. It doesn’t weigh the hair down or leave any greasy residue, which is a big plus for maintaining volume and natural movement. The mist application is super easy and ensures even coverage, making it a quick and efficient addition to any hair care routine. The pleasant, subtle fragrance is another bonus—it’s fresh without being overpowering. My clients have commented on how much they love the scent and the overall feel of their hair after using this product. The science behind K18 Pro Mist is truly impressive. It repairs damage caused by heat styling, coloring, and environmental stressors, making it a versatile solution for a wide range of hair types and conditions. I’ve seen incredible transformations in my clients’ hair, from brittle and lifeless to vibrant and resilient. I highly recommend K18 Pro Mist Professional Molecular Repair Hair Mist to any stylist looking to elevate their service offerings and to anyone serious about hair health. This product is worth every penny and has become an indispensable part of my professional toolkit. Five stars all the way!

Rated 5 out of 5 by from Hair healing elixir! This stuff is magic. I am so glad they made a bigger bottle for it. I want it hooked up to a fire hose, but it's expensive, so a bigger bottle is fine.

Rated 5 out of 5 by from Won’t do another chemical service without it I received this from Influenster, but have already been using this product since it hit the market. Love this spray, especially in conjunction with the hair mask. I have waist-long hair that was badly damaged by a lightening session a few years ago and resulting in my hair breaking off at almost my scalp. I’m still getting my hair lightened (perhaps against my better judgment) but using this before a bleaching session has DRASTICALLY reduced the amount of damage my hair has. Highly recommend for anyone doing intense chemical services.

Rated 5 out of 5 by from Repair mist! I received the K18 Professional Molecular Repair Hair Mist for review. This product is proven to reverse hair damage in four minutes from chemicals, heat tools, and bleach/color. You can use this before or after a chemical service to help your hair from feeling damaged, or just as a treatment. I tried it before coloring my hair, and my hair did not feel as damaged after. It felt stronger, shinier, and healthier. I also used it as a treatment on my hair when it was damp. It is very concentrated so you don’t have to spray much. Also smells delicious which I always appreciate. I love the feel of it on my hair and it definitely helps with damage from the many things I use on it! Recommend using if your hair is in need of repair or if you want to keep your hair, feeling strong and healthy.
