Oil Applicator Comb

What it helps with

Dandruff is linked to Malassezia, a yeast that lives on nearly everyone's scalp and feeds on sebum. Physically loosening flakes and buildup, then cleansing them away, is the part of the routine that actually targets it — which oiling alone doesn't.

A tool for your wash routine, not a treatment. Persistent, painful or spreading flaking is worth a dermatologist's time.
