| Treatment | First sign to look for | Visible improvement | Peak / plateau | Notes |
|---|---|---|---|---|
| Topical minoxidil | Less shedding by 6–10 wks | 3–6 mos | 6–12 mos | Upfront shed is common; daily adherence matters. |
| Oral minoxidil (off-label) | 4–8 wks | 3–4 mos | 6–12 mos | Often faster than topical; higher chance of systemic side effects. |
| Finasteride (oral) | Shedding reduction 1–3 mos | 4–6+ mos | ~12 mos | Most proven DHT-lowering option (men). |
| Topical finasteride | 2–3 mos | 4–6+ mos | ~12 mos | Lower systemic exposure; consistent application required. |
| Dutasteride (off-label US) | 1–2 mos | 3–6 mos | ~12 mos | Stronger DHT suppression; discuss risks. |
| Spironolactone (women) | 2–3 mos | 4–6 mos | 6–12 mos | Anti-androgen; avoid in pregnancy. |
| Ketoconazole shampoo | Scalp comfort 2–6 wks | 2–4 mos | 4–6 mos | Anti-inflammatory/sebostatic; supportive role. |
| Latanoprost (topical) (off-label) | 8–12 wks | 3–6 mos | 6–12 mos | Prostaglandin analog; mixed scalp data; avoid eye contact. |
| Thyroid replacement (T4/T3) for true hypothyroidism | 8–12 wks | 3–6 mos | variable | Only when clinically indicated; medical supervision. |
| Treating telogen effluvium | Shedding slows 6–8 wks | 3–6 mos | 6–9 mos | Remove trigger; support sleep/nutrition/stress. |
| Hair transplant | Grafts shed 0–4 wks | New growth 3–4 mos | 12–18 mos | Final “maturation” ~18 mos; maintenance still needed. |
| Microneedling | 6–10 wks | 3–6 mos | 6–12 mos | Weekly/biweekly typical; synergistic with minoxidil. |
