By now we're all well aware of the fact that mega-viral. When this happens, it seems like every other video you see features the product, and all your friends have suddenly started talking about it. The K18 Leave-In Molecular Repair TikTok users have called it a "miracle worker," adding softness and shine to hair, repairing damage and more. And some users have even added that it's better than other popular treatments on the market. But with a price tag of $75 for a full-size bottle (trial sizes start at $15), it's not something that you want to just add to your cart blindly. So we consulted with two dermatologists to get their thoughts on the product and understand how it works (and if it really does). What is the K18 hair mask? Founded in 2020, K18 currently only has one product available on its site for shoppers: The Leave-In Molecular Repair Hair Mask. (There is a handful more available for professionals). The mask is a leave-in treatment that is designed to help repair damage caused by bleach, color or heat and add strength, softness shine and bounce. It features the proprietary K18Peptide, which the brand says travels deeper into the inner layers of hair than other products to help reverse damage at a molecular level. Shop How does the K18 hair mask work? To understand how exactly the mask works, we first have to delve into the science of peptides. "Peptides are basically small proteins that penetrate the hair follicle and support hair growth," says Dr. Snehal Amin, c...

Think of your hair as a ladder that is made up of bonds. Disulfide bonds are the horizontal rungs of the ladder. There are also polypeptide chains that are the sides of the ladder, connecting the rungs vertically. When our hair undergoes any type of damage, those horizontal disulfide bonds can be broken — hence why bond builders have become more popular before, during, and after chemical treatments, explains K18 works at a deeper level to molecularly change and repair the polypeptide chains that have been broken, as well as reconnecting the disulfide bonds. "K18 replicates the entire structure of these polypeptide chains," says Sahib. "When they break, [K18] goes in there and reconnects them as if they weren't damaged, bringing the chains back to the state that they were before they got chemically damaged. It mimics the structure." Both Ford and Koestline could not confirm how deep K18 actually...

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, W editors put it to the test, and gave their honest opinions. We only include products that have been independently selected by W’s editorial team. However, we may receive a portion of sales if you purchase a product through a link in this article. Allia Alliata di Montereale, Special Projects Editor What is your day-to-day haircare routine? I love my thick, curly, long hair, but I do very little to maintain it. My hair has a life of its own and I have accepted this. Generally, I wash my hair every other day then use a leave-in conditioner and hair oil. I rarely use hydrating treatments and have not used the K18 Peptide treatment before. Discuss in detail your experience using this product. 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 . How did your hair feel after? Would you use the K18 peptide hair treatment again? 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 chang...

As far as application goes, it takes some getting used to since it’s different from your average mask. Instead of letting it sit on wet hair for up to 10 minutes and rinsing it out, you use it as a leave-in treatment. “We tell our clients to shampoo their hair, but do not condition,” says DeBolt. “After getting out of the shower, towel-dry hair well. Apply two to three pumps onto your palms and rub together to distribute evenly over hands. Begin application of the mask first onto the most porous and most sensitized parts of hair: the midlengths and ends. Then, using what little product is remaining on your hands, apply closer to the root. Use either a wide-tooth comb or a detangling brush to brush hair out and distribute product more evenly.” Be sure to let it sit for four minutes to activate, after which you can add other styling products or style with heat as usual. Though it feels somewhat unnatural to skip conditioner and apply a mask fresh out of the shower, after doing it a few times I can’t really imagine going back to traditional masks. There’s no killing time in the shower while it does its thing or getting out to let the mask sit and then back in to rinse. The mask quickly absorbs into your hair with minimal residue and is very lightweight—moreso than a traditional conditioner or leave-in—making it a great option for finer hair like mine.
