K18 Leave-In Hair Repair Mask, 50ml

Product Information

The professional option — which includes a mist and the leave-in mask — may not be as intuitive as other standalone treatments, though. "It's not confusing, but you do need to memorize when to use what product and how much you leave the product in before rinsing," says Austin-based hairstylist Daniel Kim. "It is a less-straightforward treatment system than others." Kim also says he would recommend this product, as his clients' hair does feel softer and more conditioned after use, but he wasn't positive if the patented ingredients in K18 were truly repairing the hair. Who Should Use K18? 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 .

It acts as a solvent by making the conditioning agents able to blend into the formulations.

Although the ingredients have “alcohol” in the name, they all behave differently and serve different functions in a formula. Many of them are very different in appearance and function from Denatured or Isopropyl (rubbing) alcohol.

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

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.

Although K18Hair is free of sulfates, parabens, phthalates, silicones, artificial colors, sodium chloride, formaldehydes, is vegan, and cruelty-free, we recommend that clients always consult their doctors as they will have individualized care plans. We are happy to provide MSDS sheet.Cetearyl alcohol is a fatty alcohol with a wax-like consistency. It is often used in hair care conditioning formulas because of its smoothing and softening qualities. It does not contain ethanol and therefore is used in products that are marketed as alcohol-free. K18 is more effective when left in. The formula is lightweight and works on the inside of the hair, so the hair is left feeling clean and light, even without rinsing it out. Can I use styling products with K18? 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. K18 is designed to be used consecutively for 6 washes and then every 3-4 washes to maintain your healthiest hair possible.

With most hair treatments being either conditioners that encase strands in superficial hydration and shine, or repairing treatments that work to patch up damage for temporary results, K18 has broken the hair care mold. Enter: the K18Peptide – a patented molecule that travels to the very innermost layer of your tresses, where it repairs broken bonds and restores hair’s strength and elasticity. Usually, repairing formulas work on the outer structures — the hair bonds. But K18 is the only brand that dreams up products to work on the vertical polypeptide bonds, molecularly changing and repairing the polypeptide chains that have been broken, as well as reconnecting the disulfide bonds. This is biotech hair wizardry for stronger, healthier strands from within.K18’s primary goal is to restore your hairs strength and elasticity by repairing the keratin chains damaged from bleaching, coloring and thermal heat. I was so impressed with the K-18 hair care line and noticed improved results almost immediately. My hair was more brushable, it had more shine, it looked healthier and it moved more freely. I noticed after about three uses, my hair started completely changing—like the entire biology of my hair shifted to the point where I felt like I had reversed several year’s worth of damage.
