pros using K18
how K18 works
Traveling into the innermost layers of hair, our K18Peptide™ renews strength along the width AND length of hair for lasting strength where it matters.
have questions?
we have answers.
why is k18 mist applied before bleaching / coloring?
K18 mist is applied before bleach or color services because it works on renewing client’s existing damage to strengthen the hair canvas pre-treatment. Restoring strength and elasticity in just 4 minutes means the stylist’s work can go further without having to edit process around damage. The K18 mist’s liquid formulation optimizes the efficacy of the K18Peptide™ by opening up the hair’s cuticle layers and getting the renewing peptide deep into hair’s inner cortex to repair broken polypeptide chains (keratin chains).
how is the k18 mist applied before a chemical service?
Follow these steps for best use:
- Prep hair by lightly misting with water.
- Apply K18 Mist section by section, the amount needed depends on client’s hair type and condition. Reference chart for approximate dosage.
- Wait 4 minutes. DO NOT rinse out. This is a good time to mix or prepare for your chemical service. You can dry hair after the 4 minutes are up, if needed.
why do i need to mist the hair with water before applying the k18 mist?
Misting the hair with water allows the cuticle layers to prepare for optimal penetration of the mist into the inner cortex. In the same way a damp sponge absorbs more water, damp hair absorbs K18.
how do you use k18 mask as part of a lighting or color service?
K18 Mask is used after processing bleach/color by following the below steps.
- Shampoo hair. Skip the conditioner.
- Towel-dry thoroughly.
- Apply K18 Mask, the amount needed depends on client’s hair type and condition. Reference chart for approximate dosage.
- Leave for 4 minutes before styling. DO NOT rinse out.
- If cutting, begin right away. Make sure to wait the full 4-minute wait period before heat styling.
- If toning, apply toner/gloss on top of K18 Mask. Process toner/gloss as required. Shampoo and rinse. Follow with a secondary application of K18 mask. Towel dry thoroughly. Style as usual.
will applying toner on top of k18 mask affect the outcome of my color?
K18 will not interfere with toner or final color. Colorists tell us K18 Mask actually improves their results, as it evens out the hair’s porosity, creating a more uniform and vibrant color application.
do you suggest using a clarifying shampoo before using k18? will k18 still work if there is a lot of product or buildup on hair?
In most cases, clarifying and/or detoxing is not needed prior to K18 use. However, if there is extreme coating of product or mineral buildup on the hair, we recommend clarifying before using K18 to clearway for our peptide to fully penetrate hair. Excess buildup can block the peptide from getting where it needs to go.

God Tier!
Before I introduce new things to my clients I always try them out on myself and loved ones. K18 was no different. After the first use I noticed an immediate improvement on both myself and others.
One thing about me is I'm truly chaotic so I wanted to see just how far I could push K18's professional products. I wanted to understand the limitations to its magic before I proceeded to use it on clients. So I lightened my own hair three times in one week (I'd never do this to a client, but I wanted to see how far I could go). My hair felt like it'd never been touched by lightener even after the third session! (See photo) I still can't believe nothing melted off and there wasn't any breakage. I don't think there's any limitations to the looks I can achieve now that I've got k18 in my arsenal!

skip the conditioner
Conditioners coat hair making it harder for our K18Peptide™ to effectively penetrate strands and get into the inner layers of hair. We like to skip it so the peptide can get right to damage sites without interruption. If strands need a little more love, you can add a leave-in conditioner once the initial 4-minute wait period is over.
clarify first
Excessive product or mineral buildup on hair can prevent our K18Peptide™ from effectively penetrating strands. If hair is heavy with buildup, start with a clarifying treatment before using K18 to remove residue that may block our peptide from getting where it needs to go.
continue use
Damage is ongoing, so clients' use of K18 should be too. This progressive treatment makes hair healthier with each use. Continue their hair renewal at home by using K18 for the first 4-6 washes, then every 3-4 washes to maintain the integrity of damaged hair.
less is more
Our Pro Mask is highly concentrated, meaning a little goes a long way. Don’t oversaturate hair and refer to our dosage chart to find the optimal amount for each client’s hair type and service.
