Scalp Serum
Scalp-as-skin thinking taken to its logical end: a leave-on treatment with hours of contact time rather than a minute in the shower. It is the fastest-growing Korean haircare category and the clearest expression of why Korean scalp care leads.

What makes it work
- Leave-on contact time is far longer than shampoo, which is the technical argument for the format.
- The nozzle applicator is functionally necessary to part hair and reach the scalp.
- Growing fastest of any Korean haircare category, driven by scalp-as-skin thinking.
Texture & format
Watery leave-on fluid applied directly to the scalp with a nozzle or dropper, formulated to leave no residue.
Frequently asked
Why use a serum instead of a shampoo for scalp care?
Contact time. A shampoo is rinsed within a minute, while a leave-on serum keeps actives on the scalp for hours, which is a stronger delivery argument for functional ingredients.
What claims are allowed?
This is claims-sensitive. Korea recognizes hair-loss care as a functional cosmetic category, but the US treats growth claims as drug claims. Formulate and word claims per target market.
