Outcomes where both Dutasteride and Minoxidil (oral & topical) have evidence — compare verdict strength side-by-side.
Approved BPH dose is 0.5 mg once daily; off-label hair-loss use mirrors the same 0.5 mg once-daily dose under a clinician. A prescription drug.
Any time of day
Oral soft-gel capsule (dutasteride 0.5 mg)
Topical 2–5% solution or 5% foam applied to the scalp (men: 5% twice daily or once-daily foam; women: 2% twice daily or 5% foam once daily). Low-dose ORAL minoxidil is off-label and clinician-titrated, typically 0.25–5 mg once daily. A drug — not an approved supplement regimen.
Any time of day
Topical 5% foam/solution (OTC) for most; low-dose oral minoxidil under a clinician for people having difficulty with topical formulations
