got questions? Get started here
is it better to use the full K18 routine?
Yes, the K18 routine was engineered to deliver your cleanest, healthiest hair for optimal molecular repair results. Before the mask and oil, our PEPTIDE PREP™ category tackles every kind of buildup to create your cleanest, healthiest hair canvas. With our molecular repair formulas, you get maximum damage repair plus additional styling benefits with the oil.
will the detox shampoo dry my hair out?
No, the detox shampoo will not dry your hair out. This non-stripping formula has a pH of 3.8-4.2 that won’t leave hair over-stripped. In a consumer study, 90%* said hair feels clean without feeling dry. *Disclaimers
how do the molecular repair hair mask and oil work together?
The molecular repair hair mask and oil work together to give you the reparative benefits of the K18PEPTIDE™ in both formulas. The oil will add additional frizz-reducing, styling, and heat-protecting properties. You can layer the oil on top of the mask after the 4-minute processing time.
will the mask block the molecular repair hair oil from penetrating?
No, the mask will not block the molecular repair hair oil from penetrating. The mask is a highly concentrated treatment without any fillers so it won’t block the oil from penetrating. Like layering different skincare products, the oil can be layered on top of the mask without impacting its performance.
is the K18peptide™ in every K18 product?
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.
