Is it better to use the full K18 routine?
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 tacklesbuildup + metals to create the cleanest, healthiest hair canvas. With our molecular repairformulas, you get maximum damage repair plus additional styling benefits with the oil. Use theDAMAGE SHIELD shampoo + conditioner to protect hair from daily damage betweenK18 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.
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 frompenetrating. 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, thepeptide helps reduce protein loss to help keep hair feeling healthy and strong.

You’re NOT dreaming!
In my 66+ years I’ve never been able to just wash my hair in the shower & only utilize 1 product, and be left with the silkiest, shiniest, healthiest hair EVER! It’s totally changed my routine, but more importantly, I can continue to keep my long, single process hair in the best condition it’s ever known! I recommend it to all of my clients, as I’m living proof of the results!

Perfect for clients
Love this take home kit for my clients! This allows them to continue to repair their hair at home so when they return to the salon their hair is in optimal condition for processing. The detox shampoo leaves your hair and scalp feeling cleansed and nourished, the mask is creamy and luxurious. I like to use the oil prior to drying and also a couple drops after for softness.
