who is k18 mask for?

K18 is safe to use on all hair types and textures, all generations, and was made to be used on all types of damage.

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.

how do i use k18 mask during a haircut or as a treatment on its own?

Follow these steps to use K18 with a hair cut or alone as a treatment service.
- Shampoo and rinse. 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.
- Wait 4 minutes. DO NOT rinse. If cutting, begin right away.
- Make sure to wait 4 minutes before heat styling or using other styling products. If needed, you may also condition or add a leave-in once 4 minutes has elapsed with K18.

can i use k18 mist + mask together?

These formulas are intended to be used at separate times during the service but work together to renew damaged hair from the inside out.

During a chemical service, K18 Mist is applied prior to chemical application. K18 Mask is applied post-service to renew damaged caused during the chemical service.

During a few services, you will only use theK18 Mist in the salon. During a perm for example, K18 Mist is applied before the perm solution, K18 mist is then reapplied again after the neutralizer instead of the mask to avoid additional weight on newly formed curls.

is k18 a replacement for conditioner?

K18 was created to restore hair’s strength and elasticity by reconnecting broken polypeptide chains (keratin chains) responsible for hair’s core structure. Detangling and conditioning benefits are often a bonus clients experience from K18 use. Once K18 Mist or Mask has been applied and you’ve waited the initial 4-minute wait period, you can add a leave-in conditioner. Most stylists tell us the K18 Mask alone provides all the necessary conditioning for their client’s hair.

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.

Totally worth it

I started out with the product on my hair because lately I have lost shine and it looked dull all the time. My hair looks so good and each time I use it my hair gets better. Now my clients want it so I have been ordering it for them. And I also feel like the molecular repair hair mist is making my colors turn out with more shine to the hair and very healthy. Worth every penny.

the next game changer

I can’t say enough about how healthy my hair felt after using the K18 Mist and Mask before and after my last bleaching session. K18 quickly became an essential part of my hair care routine. I highly recommend incorporating it in your existing hair care routine.

Great Results!

I have used this in conjunction with the K18hair mist on myself and my clients with their color, color, relaxers and other salon hair services. It makes fine hair feel a little thicker and has body. My hair felt softer, smoother and shinier. I can't wait to see what happens in a few months. I definitely recommend this and the K18hair mist.

Where have you been all my life!

K18 is amazing. It has transformed my hair from dry, frizzy and brittle to soft, beautiful, and almost frizz free hair. I dye my hair every 5-6 weeks ( since I was 17) and it has wrecked it. I am 57 and gave up on ever having soft, beautiful hair ever again. And one day I came across an ad about K18 and decided to try it, and I am so glad I did. Thank you K18 for giving me my beautiful hair back. The transformation didn’t take place overnight like it does for some but over a few weeks it did it’s magic. I swear by this product.
