got questions?

Get started here

Is it better to recommend the full K18 routine?

Yes, it is better to recommend the full K18 routine for your client’s cleanest, healthiest hair and optimal molecular repair results. Before the mask and oil, our PEPTIDE PREP™ category tackles every kind of buildup to create their cleanest, healthiest hair canvas. With our molecular repair formulas, they get maximum damage repair plus additional styling benefits with the oil. Your clients can use the K18 routine at home to keep their healthy hair going in-between appointments.

Will the detox shampoo dry my client's hair out?

No, the detox shampoo will not dry your client’s 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™ shampoo 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™ shampoo, the peptide 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.
