Updated November 3, 2026
Glycolic acid concentrate clears sebum plugs and refreshes oily scalps; no density gains.
What the community says
A pre-shampoo glycolic acid scalp concentrate for oily, congested scalps, especially when sebum plugs are the problem. It leaves the scalp feeling cleaner, but do not buy it expecting increased hair density; the community did not see that.
