sourced from the volcanic island of hachijo-jima, ashitaba is an ancestral Japanese plant with extraordinary self-regenerating virtues. when ashitaba’s stem is sliced, it oozes a precious golden sap and a day later, a new leaf appears. our tokyo laboratories have infused the entire ashita supreme collection with this precious ingredient.

this multi-dimensional fragrance is inspired by the home of the ashitaba, the sub-tropical forests of hachijo-jima. scents that embody the rich, volcanic soil and island sea spray are layered with notes of star anise, jasmine flower, and patchouli to create a warm and citrusy aroma.

How to use

after cleansing with ashita revitalizing scalp scrub or shampoo, followed by the ashita conditioner or mask, then dry hair as desired & apply ashita supreme hair serum to hair lengths and tips. note: use on dry hair for best results.
