What it is
The industry's first foam booster serum for in-bath hair. Give color- and heat-damaged hair a salon-like feel every time you use it. Formulated with cuticle repair ingredient "Tostear," which utilizes the heat of a hair dryer. Plus, the repair formula "keratin," along with highly moisturizing and hair-softening ingredients, delivers both shine and manageability. This in-bath treatment emphasizes results: "You'll see the difference just by drying."

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.

We're working on rolling out prepaid duties for more countries soon.
