K18 Leave-In Hair Repair Mask, 50ml

Product Information

Process your lightener or color as usual, then rinse and shampoo with K18 PEPTIDE PREP™ detox shampoo. Do not condition. To avoid weighing down fresh curls, it is not recommended to use the K18 professional molecular repair hair mask or oil immediately after completing a perm service. Wait 4 minutes (do not rinse), then apply 1-3 drops of K18 molecular repair hair oil to mid-lengths and ends. Towel dry hair, then apply 1-3 pumps of K18 professional molecular repair hair mask based on your client’s length and density, only to the ends and mid-lengths (avoiding the root).

Comb and style your hair as usual – it’s fine to add any heat protectant or styling products at this stage. I always worry that my hair will feel greasy after using moisturizing products/treatments, but this dries naturally and doesn’t leave any residue. I would say that maybe my hair is too damaged for this to repair, as I did notice it felt softer, but there definitely are still a lot of split ends in there. The K18 Leave-In Molecular Repair Hair Mask is an award-winning haircare product—it’s been compared to (and is purportedly more effective than) the industry standard, Olaplex’s No. 8 hair mask. K18’s hair mask has even been hailed as a replacement for conditioner. Does it actually work? Four W editors put it to the test, and gave their honest opinions. 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.

If toning, use K18 PRO mist first, wait 4 minutes, then apply toner directly over PRO mist. Process as usual. Rinse or shampoo toner + apply K18 PRO mask per instructions above. For cases of extreme metal + mineral buildup, process up to 10 minutes, then proceed with the instructions. In comparison, Olaplex uses patented Olaplex Bond Building Technology ™, that rebuilds broken disulfide bonds to restore strength. The brand's popular weekly pre-shampoo treatment repairs and prevents damage, whereas the K18 mask works to restore your hair to its previous state. Before the service, apply K18 professional molecular repair hair mist. Wait 4 minutes. Do not rinse out. The K18 professional molecular repair hair mask is meant to be used as the second part of the K18 molecular repair service.

Apply a minimum of 10 full sprays of K18 professional molecular repair hair mist per quadrant, increasing up to 20 sprays as needed, depending on client’s length, density, or level of damage. For best results, we recommend to use K18 chelator before every service. If not using K18 chelator, lightly dampen hair with water (do not saturate) before applying K18 PRO mist. Towel dry thoroughly, then re-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. K18 is suitable for use on all human hair extensions (to include tape-in, k-tip, hand tied, clip-in, sew-in, etc.). For information on using K18 on clients with previously installed extensions, please follow the instructions for the specific service being performed.

Ensure to clarify your hair before using the mask by using K18 PEPTIDE PREP™ Detox Shampoo. Use for 4-6 shampoos in a row for progressive results. 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, or level of damage. My hair has been dehydrated with the sun and heat damage of summer, so this was perfect timing to try K18. It was not time-consuming. I used it every time I washed my hair for two weeks, and used about 3-4 pumps each time because of my long hair. I thought using it every time I washed my hair might be overkill, but for how coarse my hair is, it works perfectly . Wait 4 minutes (do not rinse out). Then follow with the recommended shampoo per your keratin straightener service instructions.
