how to use molecular repair mask
1. Shampoo, do not condition. Towel-dry thoroughly.
2. Apply 1-3 pumps based on your length and density, starting at the ends and working up towards the roots.
3. Let sit for 4 minutes. Do not rinse out.
4. Comb, add styling product + style as usual. Use for 4-6 washes, then as needed.

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 the application of synthetic biology, we are able to do more with less, simplifying formulations and routines to support hair health and expression at home and in the salon.
K18PEPTIDE™
K18PEPTIDE™ repairs hair at a molecular level across multiple types of bonds including polypeptide chains and disulfide bonds to reverse damage from bleach, color, chemical services, and heat*. Developed through biotechnology, the K18PEPTIDE™ is optimized for human biology and uniquely matches and clicks into hair’s keratin structure, reconnecting damage sites at the molecular level, K18PEPTIDE™ delivers durable repair for all hair types, restoring strength and elasticity.
This peptide was designed in accordance with our less-is-more formulation philosophy to simplify and minimize steps in hair routines. This biomimetic molecule laid the foundation for our biology-first approach to haircare and works in just four minutes, with no extra steps, and with results shown from the very first application. For salon use, find it in the K18REPAIR™ service (K18 professional molecular repair hair mask and PRO molecular repair hair mist), and for home use, find it in the molecular repair hair mask and molecular repair hair oil.
odorBIND™
odorBIND™ revolutionizes what’s possible when targeting and eliminating odors. Using biotechnology and synthetic biology, K18 bioscientists utilized DNA databases to find and mimic the strongest olfactory systems (our sense of smell) found in nature. odorBIND™ harnesses that understanding of nature and biology to uniquely recognize, trap, and eliminate malodors, rendering them undetectable and releasing a subtle fragrance in their place. This smart-release molecule is vegan, cruelty-free, and certified Kosher and Halal. Find it inAirWash™, the reinvention of dry shampoo.
resilicore™
Patented resilicore™ heat-shielding technology protects from heat deeper than ever before*. Unlike traditional heat protectants that only coat hair’s cuticle, the size + molecular makeup of resilicore™ allows it to penetrate into hair's core to defend against heat from the cuticle to the cortex*—as deep as heat damage goes. Inspired by proteins in nature that can withstand extreme temperatures, this protective shield fortifies hair from within for maximum protection against color fade, dry feeling, dullness, and breakage. This heat-shielding tech is inspired by nature, and recreated in the lab to be vegan, sustainable + and cruelty-free. Find it inHeatBounce, the future of heat protection.
triple-action technology
TripleBright is powered by K18 triple-action technology: ionic detox, precision violet technology, and a biopolymer.
Ionic detox removes brass-causing metals + minerals. It removes up to 3 months of brass from hard water minerals and metals in 1 wash*.
Precision violet technology neutralizes existing brassiness without staining or overtoning.
Biopolymer defends against future brass by helping prevent the reattachment of metals and minerals in future washes. Find it inTripleBright, the future of blonde care.

how does the k18 mask work?
how does the k18 mask work?
The K18 mask works as a treatment to reverse damage in 4 minutes. It’s powered by our biomimeticK18PEPTIDE™to seamlessly fit in and reconnect broken polypeptide chains at the molecular level. As a result, disulfide bonds are also reconnected for reinforced strength along the length + width of hair—offering comprehensive, lasting, and progressive repair

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?
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.
