RISHIRI Hair Coloring Treatment combines premium natural ingredients, including Rishiri Kelp Extract from the northern island of Hokkaido, Japan.
This gentle, plant-based formula colors your hair while deeply conditioning it, leaving it smooth, shiny, and healthy.

Unlike the Coloring Shampoo, the Treatment delivers a more noticeable color result in just one use, making it ideal for those who want quick and vivid coverage for gray hair or to refresh their hair color in a single session.

After shampooing, towel-dry your hair well. Apply a generous amount of RISHIRI Hair Coloring Treatment evenly throughout your hair, ensuring all areas are covered.
Leave it on for about 10–15 minutes (for deeper color, leave up to 30 minutes), then rinse thoroughly with warm water.

The color develops more deeply with each application. You can use it as often as you like — even daily.
The more frequently you use it, the richer and more consistent the color becomes.
Results may vary depending on your hair type and condition. Suitable for both men and women.
