PRODUCT DETAILS

When roots look flat or thin, or your scalp feels flaky, this concentrated leave-in serum gives you targeted care where you need it. It conditions the scalp and supports fuller-, denser-looking hair from the roots.

Rosemary, PDRN, EGF and caffeine come together in nourishing care for a refreshed, balanced-feeling scalp. Ultra-fine spicules help the formula distribute more evenly, adding precision to the scalp-care experience.

The finish keeps things light: fast-absorbing and cooling, with no greasy residue and no intended loss of natural root volume. You get a fresh feel without turning root care into a heavy layer.

The mini gua sha-style tip brings targeted application and gentle scalp massage into one compact design. The formula suits wavy, curly, straight and coily hair, including dry, oily and normal types, so your texture doesn't have to decide the fit for you.
