A scalp serum from Ryo — one of Korea's most trusted heritage haircare brands — with a built-in massage ball applicator that delivers the serum straight to the spots that need it most: itchy patches, flaky areas, or dryness around the parting and crown. Twist the head to "on," glide it across the scalp, and the rolling ball dispenses the serum while gently massaging it in. No mess on your hands, no product wasted on the lengths of your hair.

The formula is genuinely well-built around two technologies: Root Repair Complex for an 18-hour moisture barrier on the scalp, and Scalp Cerasome — a ceramide, cholesterol, and lipid layering system that mimics the scalp's natural barrier structure to repair damage from heat styling, weather, and stress. Lightweight, fast-absorbing, and built for sensitive scalps that flare up regularly.

Best For: Dry, itchy, flaky, or weakened scalps — especially good for anyone whose scalp gets irritated from heat styling, hard water, or seasonal changes, and who wants targeted relief without coating the whole head.
