What is K18?
K18 is a professional hair repair mask that uses a patented biomimetic peptide — the K18Peptide™. This peptide is designed to repair the polypeptide chains in hair that have been damaged by bleaching, coloring, heat, or chemical treatments.
Unlike traditional hair masks that only coat the outside of the hair, K18 works from the inside out. It repairs the internal structure of the hair at a molecular level — similar to what a keratin treatment does, but at home and in 4 minutes.
How do you use it?
The power of K18 also lies in its ease of use:
- Wash your hair with shampoo — do not use conditioner
- Lightly towel dry your hair
- Apply a small amount of K18 throughout the hair
- Leave in for 4 minutes — do not rinse out
- Style as usual
That's all. No rinsing, no hours of waiting. The peptide remains in the hair and continues to work with each wash.
What are the results?
After the first use, you will already notice a difference in the texture of your hair. After 3-4 treatments, the results are significant:
- Less breakage — hair is stronger and more resilient
- More shine — hair cuticles lie smoother
- Less frizz — even in humid weather
- Softer texture — hair feels healthier
- Better color retention — colored hair retains its color longer
Who is K18 suitable for?
K18 is ideal for anyone with damaged hair, but particularly for:
- People who regularly bleach or color their hair
- Frequent use of straighteners, hairdryers, or curling irons
- Hair that feels brittle, dull, or dry
- Those who want to avoid a keratin treatment but desire smooth, healthy hair
It works on all hair types — from fine to thick, from straight to curly.
Is it worth the price?
K18 is not an inexpensive product. But compared to a salon treatment or keratin treatment (which can easily cost €150-300), it's a fraction of the price — with comparable results that you achieve at home.
A little goes a long way: for shoulder-length hair, you only need a small amount per treatment. A bottle can therefore last for weeks to months.
Conclusion
K18 is one of the few hair products that truly delivers on its promises. If your hair is damaged by chemical treatments or heat, this mask is one of the most effective solutions you can use at home.
