What your hair needs changes from time to time—so should your wash day routine. K18 has you covered with healthy hair routines for every day of the week. Get to know these biotech-powered routines, both for when you need to repair damage and defend against it.

The treatment day routine works to reset hair and reverse damage with the PEPTIDE PREP™ detox shampoo and leave-in molecular repair hair mask. 

The color-safe, non-stripping detox shampoo gently but effectively removes 99% product buildup*, 95% sebum* + 76% copper* for detoxified, refreshed hair. This clarifying cleanse works to clear the path for maximum K18 mask results.

The K18 mask reverses damage in 4 minutes from bleach + color, chemical services, and heat* for immediate + lasting results. Think of this like a reset button for damaged hair; you can expect stronger, softer, smoother, bouncier hair after the first use.

We recommend using this for the first 4-6 washes after noticing hair damage (breakage, split ends, dryness, dullness) or after color and chemical services in the salon. After that, switch to the daily protection routine to maintain hair health in between K18 mask days, and use the detox shampoo + K18 mask weekly. 

Start here for healthy hair:

Protect your hair from ongoing damage with the DAMAGE SHIELD pH protective shampoo and protective conditioner. This daily defense duo protects hair from daily damaging elements, like UV rays, environmental aggressors, and mechanical styling.  Now you can help prevent additional damage between molecular repair treatment days. 

The DAMAGE SHIELD pH protective shampoo includes the K18PEPTIDE™ to help maintain hair health through washing Did you know lathering up can cause mechanical damage at hair’s most vulnerable moments (when it’s wet)? The DAMAGE SHIELD shampoo is a pH-optimized formula (4.5-5.5) that helps prevent excess swelling of the hair cuticle to help prevent damage, reduce frizz, preserve color, and maintain health and shine. This optimized pH also helps preserve the scalp microbiome, making this shampoo gentle enough to use every time you cleanse.

The DAMAGE SHIELD protective conditioner is hair’s first defense against daily damage. This nourishing conditioner acts as shield against daily damage, fortifying, softening, and detangling hair while helping provide conditioning protection against damage from daily mechanical styling, UV-rays, and environmental aggressors for up to 3 days*. 

Use the DAMAGE SHIELD shampoo + conditioner in-between K18 mask days to maintain your healthiest hair. This can look like using the K18 detox shampoo + mask for 4-6 wash days, then switching to the DAMAGE SHIELD shampoo + conditioner to protect against daily damage—until the next time you need a damage repair reset.
