The molecular repair hair mask and oil work together to give you the reparative benefits of the K18PEPTIDE™ in both formulas. The oil will add additional frizz-reducing, styling, and heat-protecting properties. You can layer the oil on top of the mask after the 4-minute processing time.

*k18hair.com/disclaimers
No, the mask will not block the molecular repair hair oil from penetrating. The mask is a highly concentrated treatment without any fillers so it won’t block the oil’s path. Like layering different skincare products, the oil can be layered on top of the mask without impacting its performance—in fact, they work even better when used together.
Our biomimetic peptide mimics hair’s natural structure to seamlessly fit in and reconnect broken keratin chains responsible for hair’s core strength and elasticity. As a result of this reconnection it also addresses cleaved disulfide bonds for connection along the Y-axis of hair AND the X-axis or width of hair.
Instead of mixing the oil and mask together, get the most effective repair and styling benefits by using the mask first, waiting 4 minutes, and then applying the oil.
Conditioner leaves a film that blocks our peptide from penetrating effectively. Once the 4-minute wait time is up, feel free to use a conditioner, a leave-in, or any type of product.

    K18 SAVED my Hair Extensions

    I absolutely love this set of K18 repair + protect minis. I’ve used the clarifying shampoo and leave-in hair mask three times and they have saved my hair extensions. I would recommend K18 to anyone that is having issues with hair damage, frizziness & dryness. You will be blown away with the results after just 1 use!

    Amazing products!!

    I was skeptical of buying k18 products because other high end products I’ve tried haven’t worked for my hair. After the first wash my hair felt and looked completely different. Little to no buildup issues. Normally my hair will have lots of buildup the day after I wash. Not with k18. My scalp is less itchy, hair is wavy, soft and less frizzy. I’ve had so many compliments on my hair since starting k18. I will definitely be buying the full size items when I get closer to running out!

    Wow! It actually works!

    5 months ago I had my hair bleached by a hairdresser and I swear she was high😂

    After the process she told me she used a 50volume and completely fried my hair. It is baby fine and naturally curly.

    I’ve had plenty of bleaching before and my hair has never broke off before. But this time it did. It was so fried. At the top my hair was literally 2 inches long in some places. So I waited and went to a better stylist who helped even out my hair and we had to cut it into a bob. It still felt super stressed, brittle, and no more curls! They were like stringy squiggly twigs. It was terrible.

    I’ve literally used everything. Bonding Redken, Aveda repair, Olaplex, quai, bondi boost, you name it…. I’ve used it. Spent hundreds of dollars on hair products to try to get my hair back feeling normal. I just used this tonight… just the prep shampoo and leave in. No other products… my hair feels like it did in my 20s after one use. Bouncy, happy, healthily feeling hair.

    I will be ordering the whole line in full sized bottles.

    I didn’t think to do a before photo but trust me it was terrible. But here is the after.

    Thank you K18!
