Yes, it is better to use the full K18 routine for optimal service and molecular repair results.
To achieve the best cumulative results, we recommend using these routines:
when you need to repair damage: detox shampoo + mask
when you need to protect against daily damage: DAMAGE SHIELD shampoo + conditioner
every day: molecular repair hair oil
between wash days: AirWash™ dry shampoo
Before K18 molecular repair mask or oil, our PEPTIDE PREP™ detox shampoo tackles buildup + metals to create the cleanest, healthiest hair canvas. With our molecular repair formulas, you get maximum damage repair plus additional styling benefits with the oil. Use the DAMAGE SHIELD shampoo + conditioner to protect hair from daily damage between K18 mask days—and keep healthy hair going in-between salon appointments. Use AirWash™ dry shampoo to refresh hair between washes with an instant, weightless clean.

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
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.
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.
Our biomimetic peptide mimics hair’s natural structure to seamlessly fit in and reconnect broken keratin chains responsible for hair’s core strength and elasticity. As a result of this reconnection it also addresses cleaved disulfide bonds for connection along the Y-axis of hair AND the X-axis or width of hair.
