It starts at the scalp.
Plant derived cleansers wash away fine dust, sebum, and buildup while Jeju cypress water cools the scalp. Hair is left soft and manageable, without silicones.
Washes the day out.
Fine dust, sebum, and buildup rinse away with plant derived cleansers. The moisture your scalp needs stays.
Cool on the scalp.
Cypress water cools the scalp as it cleanses, and on sensitive skin the formula reads as low irritation.
Three minutes of forest.
A dense lather carries the scent of the cypress forest while the water runs. Rinsed and dried, hair is left soft and glossy.
Jeju Hinoki Cypress water.
Branches pruned this year from roughly thirty year old cypress trees in Ara-dong, Jeju, hand-gathered without machinery, steam-distilled for two hours with the Jeju Resource Plant Research Institute. What remains after distillation is composted and returned to the forest. In this bottle, that water comes first: it is the first ingredient in the formula.
Hinoki Cypress oil
The only added scent, from the same two-hour distillation.
Tangerine peel extract
One of three botanical extracts in the formula.
Centella asiatica extract
The botanical better known as cica.
Jeju dwarf bamboo extract
Sasa quelpaertensis, gathered on Jeju.
