K18PEPTIDE™ is a biotech-developed peptide that mimics hair's structure to reverse damage by reconnecting polypeptide chains and disulfide bonds broken during damage from bleaching and chemical services.

K18 molecular repair + PEPTIDE PREP™ shampoos are formulated with the K18PEPTIDE™. In our molecular repair products, the peptide works at the innermost layers to reverse hair damage. In our PEPTIDE PREP™ shampoos, the peptide helps reduce protein loss to help keep hair feeling healthy and strong.

The K18 mask works as a treatment to reverse damage in 4 minutes. It's powered by our biomimetic K18PEPTIDE™ 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.

You should use the K18 mask because we put our hair through a lot. if you're someone who expresses themselves through their routine, or frequents the salon for bleach, colour, or other chemical services, K18 was engineered for you. If you just live your life with hair, you also need it, since just walking outside and exposing hair to sunlight or pollution can cause chemical reactions and damage. Think of K18 as that multivitamin for your hair, the first step in a healthier routine that makes all those other efforts go further.

You need both shampoos to get the most effective clean while maintaining your hair + scalp health. Detox shampoo is engineered for less frequent heavy duty washing, and pH maintenance shampoo is engineered for frequent, everyday washing.

While the molecular repair hair oil and HeatBounce have heat protection benefits, HeatBounce defends against heat from the cuticle¹ to the cortex², going as deep as heat damage goes to help protect against colour fade, dry feeling, dullness, and breakage. The oil delivers traditional heat protection on the outer layers of hair and clinically proven damage repair.
