Rogaine (topical) / generic oral minoxidil

Finasteride and minoxidil work through different mechanisms and are often combined for best results. Finasteride is an oral 5-alpha-reductase inhibitor that lowers DHT — the hormone driving male pattern hair loss — addressing the root cause. Minoxidil (topical or oral) increases blood flow to hair follicles and prolongs the growth phase, addressing the downstream symptom. In studies, the combination produces meaningfully better outcomes than either drug alone: combination users see more regrowth and better maintenance over time. Side-effect profiles are different (finasteride has potential sexual side effects; minoxidil can cause shedding initially and unwanted facial hair if applied carelessly). Most telehealth services offer both as a combined protocol.

Topical minoxidil side effects are usually mild: scalp irritation or dryness, contact dermatitis at the application site, and unwanted facial or body hair if the solution migrates (avoid by applying with clean fingers, letting it dry fully before touching face). Initial increased shedding around weeks 4-8 is common and usually signals the medication is working — established weaker hairs are pushed out as new growth begins. Oral minoxidil (a newer off-label trend for hair loss, originally a blood pressure medication) carries more significant potential systemic effects: low blood pressure, dizziness, fluid retention, increased heart rate, and unwanted hair growth in unwanted locations. Oral minoxidil should only be used under clinical supervision with baseline cardiac screening. Both forms require ongoing use — discontinuation reverses the effect over 3-6 months.
