Frequently Asked Questions

How is this different from the original K18 Hair Mask?

The repair technology is the same patented K18PEPTIDE™ formula, but this limited-edition version is infused with Future Society’s Floating Forest fragrance for a unique sensory experience.  

Do I rinse the mask out?

No. It is a leave-in treatment designed to remain in the hair after application.  

Should I use conditioner before applying it?

No. K18 recommends skipping conditioner before application so the peptide can fully penetrate the hair fiber. You may use styling products after waiting 4 minutes.  

How often should I use the mask?

For heavily damaged hair, use after every shampoo for the first 4–6 washes, then reduce to maintenance use every 3–4 washes or as needed.  

Is it suitable for color-treated or bleached hair?

Yes. It is specifically formulated to repair damage caused by bleaching, coloring, chemical treatments, and heat styling.  

Can all hair types use this product?

Yes. The lightweight formula is suitable for fine, medium, thick, straight, wavy, curly, and coily hair types
