      our story

      Our story began with a decade of complex research into the bioscience of hair,resulting in our patented molecular repair peptide. Through this research and theapplication of synthetic biology, we are able to do more with less, simplifyingformulations and routines to support hair health and expression at home and inthe salon.

      odorBIND™

      odorBIND™ revolutionizes what's possible when targeting and eliminating odors.Using biotechnology and synthetic biology, K18 bioscientists utilized DNAdatabases to find and mimic the strongest olfactory systems (our sense of smel)found in nature. odorBIND™ harnesses that understanding of nature and biologyto uniquely recognize, trap, and eliminate malodors, rendering them undetectableand releasing a subtle fragrance in their place. This smart-release molecule isvegan, cruelty-free, and certified Kosher and Halal. Find it in AirWash™, thereinvention of dry shampoo.

      Patented resilicore T heat-shielding technology protects fromheat deeper thanever before*. Unlike traditional heatprotectants that only coat hair's cuticle, thesize + molecularmakeup of resilicore™allows it to penetrate into hair's coretodefend against heat from the cuticle to the cortex* -as deepas heat damagegoes. Inspired by proteins in nature that canwithstand extreme temperatures, thisprotective shield fortifieshair from within for maximum protection against colorfade, dryfeeling, dullness, and breakage. This heat-shielding tech isinspired bynature, and recreated in the lab to be vegan,sustainable + and cruelty-free. Find itin HeatBounce, the futureof heat protection.

      triple-actiontechnology

      TripleBright is powered by K18 triple-action technology: ionic detox, precisionviolet technology, and a biopolymer.
      onic detox removes brass-causing metals + minerals. It removes up to 3 monthsof brass from hard water minerals and metals in 1 wash*.Precision violet technology neutralizes existing brassiness without staining orovertoning.
      Biopolymer defends against future brass by helping prevent the reattachment ofmetals and minerals in future washes. Find it in TripleBright, the future of blondecare.

      why skip conditioner?

      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.

      i noticed there's alcohol in the formula, isn't that bad for you?

      We like to keep our formulas minimal, only using the exact amount of ingredients needed to get the peptide where it needs to go. Here the alcohol serves as an agent to optimize the hair environment for the K18 mask to work on a deeper level. Our unique blend of 3 alcohols functions to open the hair cuticle so theK18PEPTIDE™can penetrate the innermost layer of hair, reaching the broken polypeptide chains (keratin chains).

      when should i expect to see results?

      Most see results after 2-3 uses. The more damaged the hair, the more dramatic the results so it may vary depending on your hair type and level of damage.
