K18 Leave-In Hair Repair Mask, 50ml

Product Information

It's worth noting that the brand recommends working it into the hair from the ends to the roots, however I did actually avoid the roots at first as I was worried about them looking (and feeling) greasy.

The K18 professional molecular repair hair mask is meant to be used as the second part of the K18 molecular repair service. I have used it multiple times since trying it the first time, so yes! I now use it at least once every two weeks. Hannah Westbrook, Assistant Visuals EditorApply 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. Wait 4 minutes after chelating**, then rinse and shampoo with K18 PEPTIDE PREP™ detox shampoo. Do not condition. Wait 4 minutes (do not rinse out) and if needed, dry the hair prior to beginning relaxer application. Strengthen your hair and improve elasticity whilst reversing the damage caused by chemical treatments, mechanical styling, and heat styling. This leave-in treatment takes just 4 minutes to reverse hair damage by harnessing the power of the K18PEPTIDE™. Working at the innermost layer of your hair, the K18PEPTIDE™ reconnects the polypeptide chains and disulfide bonds that are broken because of chemical services, heat damage, and bleaching services. The peptide helps to renew strength and elasticity, giving you healthier, bouncy hair – even in cases of severe damage. Wait 3-4 shampoos post-treatment before using the K18 molecular repair hair mask in the salon or at home.

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. Before the service, apply K18 professional molecular repair hair mist. Wait 4 minutes. Do not rinse out. 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. My daily haircare routine consists of a cold shower and letting my hair air dry. That’s it! I’m a big believer in air drying so that your hair curls naturally. I’ll use Moroccan oil shampoo and conditioner three times a week, but I can’t shampoo any more than that, otherwise my hair will become super dry. I’m really a less-is-more kind of hair guy, so it’s safe to say I’ve never done anything like the K18 treatment before. 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.

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. When using the K18 Leave-In Molecular Repair Hair Mask, did you follow the directions step-by-step or modify them at all? 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.

I was hesitant about not using conditioner and using K18 as a leave-in conditioner instead, but it made my hair feel significantly softer. I like how it is not heavy or does not change the weight of my hair. I still used my hair oil to control frizz, but my hair is naturally on the frizzier side. I saw real results in a short amount of time. I loved it and will continue using it! This size of the bottle is also perfect for traveling this summer. Jenna Wojciechowski, Fashion Market Editor 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. 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. By reconnecting these polypeptide chains, the mask strengthens along the length and width of the hair, offering a full 360 approach.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. For cases of extreme metal + mineral buildup, process up to 10 minutes, then proceed with the instructions.

Towel dry hair, 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. Wait 4 minutes (do not rinse out). Then follow with the recommended shampoo per your keratin straightener service instructions. Comb and style your hair as usual – it’s fine to add any heat protectant or styling products at this stage.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. 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 .
