more to know

K18 Professional Mist is the pre-service part of our 2-step in-salon service. Our mist was engineered to make hair strong enough to withstand damage that occurs during a chemical service. The pH level of 7.5-8.0 shifts the cuticle layer to penetrate into hair’s cortex and hone in on damage sites, resetting the hair's healthy canvas before exposing it to the damage of bleach, color, or other chemical services.

K18 Professional Mask is a post-service part of our 2-step in-salon service or can be used as a stand-alone treatment for clients. This mask was engineered to repair damage caused during any salon service. With a pH of 5.0-6.0, the leave-in mask helps to close the cuticle and seal in the peptide to reconnect broken keratin chains, with added lightweight conditioning benefits to keep hair smooth and soft.

creates hair like new

Traveling into the inner-most layers of hair to reach the core polypeptide chains (keratin chains), our revolutionary K18Peptide™ is just the right size and makeup to fit in and reconnect broken keratin chains. You can feel and see the difference with the first use.

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.

renews strength, softness, smoothness, and bounce

AZURE’s stylist prepped hair before her bleaching service with K18 Pro Mist to restore her healthy canvas before undergoing the platinum service. Post-bleaching, the stylist treated hair with the K18 Pro Mask to restore elasticity and bounce.
KAREN had damage from previous relaxer services. This time, she received the K18 2-step pro service with her relaxer treatment for smooth, silky hair pre and post-service.
CHELSEA came into the salon with dry, brittle strands from frequent heat styling. Her stylist started with the K18 Pro Mist to restore strength and health to hair before going through her lightening service. After her highlights, her stylist used the K18 Pro Mask treatment to repair any damaged caused during the highlight service.

Lalalove it!!!

The repair mask works great !! My clients hair feels amazing after their chemical service!!! Here are before and after pics. The shorter hair client has super curly fragile hair. My long hair client had box dye in her hair so I had to strip her color out and then I did highlights and color. They were amazed how their hair came out. I can’t wait to use the hair mist.

It’s hard to explain the mist, but using it before a color or a bleach…I feel like I am safe!!

I have noticed more shine and strength though!

client recommendation

At-Home Treatment

Leave in Molecular Hair Repair Mask

2 pumps

Use for the first 4-6 washes, then every 3-4 washes for ongoing damage repair.

optimize K18

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.

more is more

When using the Pro Mist, the more the merrier to reset damage before a chemical service. Use pre-service for a healthy canvas by applying a generous amount of the Pro Mist to damp hair, section by section.
