Volcanic Minerals & 0.5% Salicylic Acid Shampoo For Dandruff-Prone Hair

Salicylic Acid — A beta-hydroxy acid that dissolves oil and dead skin inside the pore, so it's the go-to for blackheads, congestion and oily-skin breakouts. The label states 0.5%. Works from ~1%. OTC cap 2%. Give it 8–12 weeks for congestion & blackheads. Best for Oily, Combination. An oil-soluble exfoliant — brilliant on oily, congested skin. On dry or reactive skin it can strip and sting, so ease in slowly.

Niacinamide — Vitamin B3 — a broadly-tolerated all-rounder that strengthens the skin barrier, evens tone and helps regulate oil. The strength is not printed, so we cannot judge the dose; that counts against the brand. Works from ~5%. OTC cap 10%. Give it 8–12 weeks for tone. Suits all skin types. One of the best-tolerated actives there is — fine for every skin type, and especially handy for oil and uneven tone.

Glycolic Acid — The smallest alpha-hydroxy acid — it resurfaces the top layer for glow and even tone, working on the surface where BHA works in the pore. The strength is not printed, so we cannot judge the dose; that counts against the brand. Works from ~8%. OTC cap 10%. Give it 4–8 weeks for tone & texture. Best for Oily, Combination, Normal. A surface exfoliant for glow and texture. It raises sun sensitivity and can irritate dry or reactive skin — daily SPF is non-negotiable.
