Proven Treatments
Two medications have robust clinical evidence for treating hair loss.
Finasteride (Oral)
- How it works: Blocks 5-alpha reductase, reducing DHT levels by ~70%
- Efficacy: 83% of men maintain or regrow hair over 2 years
- Dosing: 1mg daily (prescription required)
- Timeline: Results visible at 3–6 months; full effect at 12 months
Minoxidil (Topical)
- How it works: Increases blood flow to follicles and extends the growth phase
- Efficacy: 40–60% of men see moderate to dense regrowth
- Dosing: 5% solution applied twice daily (OTC)
- Timeline: Initial shedding is normal; results at 4–6 months
Combination Therapy
Using both medications together is more effective than either alone:
| Approach | Hair Count Increase (12 months) | |----------|-------------------------------| | Finasteride only | +10–15% | | Minoxidil only | +8–12% | | Combined | +20–30% |
Side Effects to Know
Finasteride: 2–4% of men report decreased libido (reversible on discontinuation) Minoxidil: Scalp irritation, initial shedding phase, unwanted facial hair growth
Consistency Is Key
Both medications require ongoing use. Stopping treatment leads to gradual return of hair loss within 6–12 months.
