Dr.Groot's premium scalp shampoo, built around one of the more interesting innovations in haircare right now: bio-exosomes. These are microscopic carriers — reportedly around 1,700 times smaller than your scalp pores — that deliver growth factors and nutrients directly to the cells that need them. The result is a shampoo that goes well beyond cleansing, with the kind of cellular-level care most scalp products only gesture at.

Underneath the exosome technology, the formula uses the three Korean-approved hair-loss-care actives — salicylic acid, niacinamide, and panthenol — to exfoliate, soothe, and strengthen the scalp. Encapsulated biotin capsules burst on contact for fresh delivery, while centella asiatica and ginseng calm and fortify. Free from sulfates and silicones, gentle enough for daily use, and a real step up if your current scalp routine isn't quite cutting it.

Best For: Thinning hair, weakened roots, or anyone whose scalp routine has plateaued and wants to step up to a more advanced formula — also good for sensitive scalps that haven't responded well to harsher anti-hair-loss shampoos.
