Can Ketoconazole Shampoo Stop Hair Loss?
Distinguishing treatment of dandruff and seborrhoeic dermatitis from evidence for androgenetic alopecia.
Main use
Ketoconazole is an antifungal used in managing dandruff and seborrhoeic dermatitis.
AGA evidence
Small studies provide limited evidence for androgenetic alopecia. A hair-growth effect equivalent to finasteride or minoxidil has not been established.
When it may help
With dandruff, itch or inflammation, it can help manage scalp disease. Correct dermatological diagnosis matters.
Risks
Dryness, irritation and contact dermatitis may develop. Use after transplantation depends on healing.
Limits of the evidence
These are selected clinical sources and expert recommendations, not a new systematic review. Formulations, participants, controls, follow-up and adverse-event reporting differ. Positive findings do not establish identical benefit or local authorisation for every patient or product.
Topic-specific questions
Does controlling dandruff prove pattern hair loss is treated?
No. Scalp inflammation and androgenetic miniaturisation are different treatment targets.
Can ketoconazole replace minoxidil or finasteride?
Equivalent hair-growth efficacy has not been demonstrated; treatment depends on diagnosis.
