With the K18 Hair Leave-in Molecular Repair Hair Mask, you can style your hair in various ways without worrying as much about causing damage. It aims to provide a solution that enhances both the health and appearance of your hair.

Prepare your hair for the K18 experience

Giving your mane the best care starts with enough preparation. To get the most out of your K18 application, ensure your hair is clean and damp, not dripping wet. Detect your hair's porosity to customise the quantity of the treatment. Lower-porosity hair would require less of the K18 peptide, while higher-porosity hair would require more.

Embrace the K18 magic in easy steps

Here’s how to use the K18 Leave-in Molecular Repair Hair Mask:

  • Apply to Hair. Apply the mask gradually from the mid-lengths to the ends of your hair, making sure it's evenly distributed.
  • Use Sparingly. Remember that a small amount of the K18 mask is sufficient.
  • Leave for Four Minutes. Allow the mask to sit on your hair for at least four minutes. This time is necessary for it to help repair your hair.
  • Do Not Rinse. Do not rinse the product out of your hair, but instead, style your hair in your preferred way.

K18 post-application care and routine

The key to sustaining your hair's newfound glory is all in the aftercare. Post-application, resist the urge to rinse it off. It continues to perform its action long after the initial treatment, supporting your hair’s health. 

For the first four to six washes, use it every time you cleanse your hair. After this period, reduce the frequency to once a week or as you find fitting for your hair needs.
