What it is
Pursuing functionality in salon work. A formula designed with high affinity to the body, centered on naturally derived ingredients. This water treatment replenishes high concentrations of protein that forms the foundation of hair, recreating supple, natural hair from the core. With a focus on high penetration, high repair, and high moisturizing, it delivers repair ingredients deep into the hair, acting like a serum in skincare. It is effective not only for repairing damage, but also for aftercare after coloring and perms, and for improving the color retention of color shampoos. It can be used in any situation, from pre-care for those concerned about heat damage from irons to fixing bedhead in the morning. A refreshing citrus scent gently spreads, leaving hair smooth to the touch and with a natural shine. *This product is a refill, so the bottle is not included.

Will I pay customs or import fees?
US orders: No. As of July 1, 2026, all US orders ship DDP (duties delivered prepaid), meaning we prepay all import duties on our end. Nothing is due at your door.
Orders outside the US: Possibly. Duties and import taxes are set by your local customs authority and are not collected at checkout, so any charges on delivery are your responsibility.
We're working on rolling out prepaid duties for more countries soon.
