The K18 professional molecular repair hair mask is meant to be used as the second part of the K18 molecular repair service.

Jon Reyman, a bicoastal hairstylist and cofounder of Spoke & Weal Salon, which has locations in Boston, Chicago, New York City, Nashville, Palo Alto, Los Angeles, and San Francisco. When bond builders were invented in the mid 2010s, the beauty industry saw the creation of an entirely new category of products that transformed color services and made possible the ultra-platinum trends we see today. Something this transformative to the pro beauty world only happens once in a lifetime…or does it? K18 is most effective on clean, towel dried hair. Conditioner formulas use silicones and conditioning agents that form heavy coatings on hair that prevent K18 Peptide from penetrating to the broken disulfide bonds within the cortex. You may use conditioner after K18 has processed for 4 minutes if needed, not before.

We do not recommend using K18 Mist or Mask prior to Brazilian or Keratin treatments. However, we do recommend that you use our K18 Mask on your first hair wash after treatment and for 6 consecutive times after.

K18Peptide™ is not able to regenerate bonds in the presence of too much water inside the cortex. However, the hair needs to be slightly damp to help with penetration of the product into the hair. The in-salon K18 Treatment promises to protect hair and lessen damage. It improves color uniformity and longevity, and adds strength, shine and manageability, according to K18 Hair. Here’s what the service looks like: If cutting, you may start right away. If toning, use K18 Mask then apply toner over K18 Mask. Process as usual. Rinse/shampoo toner, reapply K18 Mask as per instructions above.K18 is not organic because only natural ingredients can be certified organic. K18 uses both natural and synthetic ingredients because we prioritize cleanliness and safety. Isopropyl alcohol is at a very low level (about 0.5%) in the K18 Mask formula. It is part of an ingredient blend, but it is not directly added to the formulas. It acts as a solvent by making the conditioning agents able to blend into the formulations. The K18 professional molecular repair hair mist is meant to be used as the first part of the K18 molecular repair service.

Cetearyl alcohol is a fatty alcohol with a wax-like consistency. It is often used in hair care conditioning formulas because of its smoothing and softening qualities. It does not contain ethanol and therefore is used in products that are marketed as alcohol-free. Before the service, apply K18 professional molecular repair hair mist. Wait 4 minutes. Do not rinse out. We highly encourage it. Our hair is not only damaged by color, but from heat, sun, products, water and environmental aggressors. K18 restores your hairs health and reverses any damage, everyone can benefit from K18. Unlike bond builders, this isn’t a temporary fix. According to Connaghan, this biosciences discovery, 10 years in the making, can progressively renew the hair’s keratin dimer structure (which is key to repairing hair) while also reconforming the disulfide bonds that traditional bond builders temporarily strengthen. K18 is more effective when left in. The formula is lightweight and works on the inside of the hair, so the hair is left feeling clean and light, even without rinsing it out. Can I use styling products with K18?For cases of extreme metal + mineral buildup, process up to 10 minutes, then proceed with the instructions. 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. Let sit for 4 minutes. Do not rinse out. 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, or level of damage.
