ScalpNest is a practical guide to scalp care: flakes and dandruff, itch, oiliness, build-up and the products that address them. Start with the buying guides for dandruff shampoos, scalp scrubs, scalp oils, scalp serums and scalp massagers.
Flaking has more than one cause, and the right product depends on which one you have, so our guides begin with the difference between a dry scalp and dandruff and explain the active ingredients — ketoconazole, zinc pyrithione, selenium sulfide, salicylic acid — in plain language. We compare products on their actives, formulas and directions, and we point you to a dermatologist when symptoms are persistent or severe. Some links earn us a commission; see our editorial policy.
