You’ve probably heard of K18by now, loved for their viral, peptide-powered leave-in hair mask that repairs damage in just 4 minutes. Yep, we know it sounds too good to be true—but it's absolutely true. We put it to the test and saw stronger, softer, smoother, and bouncier hair that lasts, and gets better the more you use it.
This Leave-In Molecular Repair Hair Mask is powered by their patented K18PEPTIDE™ to repair damage from bleach + color, chemical services + heat in just four minutes.
It works in the innermost layers of hair (where all hair is the same) for lasting hair health on ALL hair types. So you don’t have to second-guess if it’ll work for you.Since then, K18 has launched two new PEPTIDE PREP™ shampoos that understand your hair for a color-safe + pH-optimized clean.
- The PEPTIDE PREP™ pH Maintenance Shampoo was formulated with your hair’s optimal pH in mind + the K18PEPTIDE™ to effectively cleanse without causing damage. This gentle formula can be used every time you wash for strong, smooth, and healthy hair.
- The PEPTIDE PREP™ Detox Shampoo is a gentle but effective clarifying shampoo with the K18PEPTIDE™ to remove 99% product buildup, 95% sebum + 76% copper for detoxified, refreshed hair. This clears any buildup blocking the K18 mask for even better results, so it’s a must to buy together.
