The treatment contains seaweed extract from the hot thermal springs of Beppu, a city in Japan famous for hot springs. A gentle, sulfate-free conditioner that does everything from rebalancing your roots to adding light hydration.

Beppu City, Oita Prefecture, where ONSENSOU was born, is the hot spring city that boasts the largest number of springs, the number of spring sources, and the types of springs in Japan.

There are nearly 3000 sources, and 10 of the 11 types of spring quality exist. From the simple question of the development team, "Why hot springs make your skin beautiful," research began with a spotlight on the "small lives" that exist in the hot springs as many as the number of stars.

As a result of many years of research, ONSENSOU finally discovered new species of "hot spring algae" and "hot spring yeast". It has been confirmed that it is a new type of microorganism with unique characteristics that can be said to be the source of hot springs. ONSENSOU is a hair care series from Japan that luxuriously blends these two hot spring ingredients.

The deep, fruity and refreshing scent of wild bluebell was specially scented in France.
