Product Information

Full details

The K18 Leave-In Molecular Repair Hair Mask is designed for individuals seeking to reverse damage from chemical, thermal, and mechanical styling. This professional-grade treatment offers the primary benefit of restoring hair strength and elasticity in just four minutes. A key caveat for users is that it must be applied to clean, damp hair without the use of conditioner, as traditional conditioning products can create a barrier that prevents the formula from penetrating effectively.

Extended Product Information

FAQs

Can I use K18 with other products?

Yes, once the four-minute wait period is complete, you can apply your usual heat protectants, oils, or styling creams.

Is this product safe for colored hair?

Absolutely. It is specifically formulated to repair damage caused by coloring and chemical processes, and it will not strip your color.

How often should I use it?

Use it for the first 4-6 washes consecutively, then move to a maintenance schedule of every 3-4 washes.

Do I need to rinse it out?

No, it is a leave-in treatment. You apply it, wait four minutes, and then proceed with your normal styling.

Will it make my hair oily?

When used in the recommended small amounts, it should not leave hair feeling oily. If it does, reduce the amount used in your next application.

Troubleshooting

Hair feels tacky or heavy after application

You likely used too much product. Start with one pump and only add more if necessary; it is a highly concentrated formula.

No noticeable improvement in texture

Ensure you are not using a conditioner before applying K18. The hair must be free of coatings for the peptides to reach the keratin chains.

Difficulty distributing the product

Make sure your hair is damp but not dripping wet. Towel-dry thoroughly before application to allow for even distribution.

Pros and Cons

Pros

  • Significantly reduces hair breakage
  • Time-efficient four-minute processing
  • Improves hair softness and smoothness
  • Cruelty-free and vegan formulation
  • Restores hair to a more youthful, resilient state

Cons

  • Requires avoiding conditioner during the wash phase

  • Requires strict adherence to application steps for best results
  • Results may vary depending on the initial level of hair porosity

Setup, Compatibility & Care

To ensure proper compatibility, cleanse your hair with a clarifying shampoo if you use heavy styling products, as product buildup can interfere with the peptide delivery. Do not apply conditioner or leave-in sprays before using the K18 mask; these products contain silicones or conditioning agents that block the repair process. After the four-minute wait, you may apply your preferred styling products or serums. Store the 50ml bottles in a cool, dry place away from direct sunlight to maintain the stability of the bioactive peptides. Use the mask consistently for the initial cycle, then switch to a maintenance schedule of once every 3-4 washes.
