Dandruff isn't just a flake problem — it's a fungal-microbiome imbalance. Malassezia yeast lives on every scalp, but in dandruff it overgrows and breaks down sebum into irritating fatty acids that trigger flaking, itching, and inflammation. Drugstore anti-dandruff shampoos use zinc pyrithione or selenium sulfide to suppress the yeast — effective short-term, but harsh for long-term scalp health.

Professional anti-dandruff routines balance active treatment with scalp barrier repair. ProHair carries Nioxin's three-step systems (the gold standard for combined dandruff + thinning), Joico K-PAK Clarifying for product buildup that mimics dandruff, Medavita's Italian Cutis Pura clay scrubs and Lotion Concentrée scalp treatments, and Schwarzkopf BC Bonacure Scalp Genesis for chronic flake control.

Whether you're dealing with seasonal flakes, chronic dandruff, scalp psoriasis flares, or just want a clean cleansing routine that doesn't trigger more flaking — this is where to start.
