Wait 4 minutes (do not rinse), then apply 1-3 drops of K18 molecular repair hair oil to mid-lengths and ends.

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. 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). 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.Apply 1-3 drops of K18 molecular repair hair oil to mid-lengths and ends on dry hair as a finisher. Wait 4 minutes (do not rinse out). Then follow with the recommended shampoo per your keratin straightener service instructions. 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 3-4 shampoos post-treatment before using the K18 molecular repair hair mask in the salon or at home. 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. 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 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. 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 .

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. 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 have used it multiple times since trying it the first time, so yes! I now use it at least once every two weeks.
