Oral vs. Topical Minoxidil for Hair Loss
The Short Answer
Oral minoxidil generally works better for most people, but with more risk.
Effectiveness
- Oral (low-dose, 0.625–2.5mg) tends to show stronger, more consistent regrowth across the scalp
- Topical (2–5%) works well but results vary more by person and application consistency
Popular Products
Topical:
- Rogaine – the classic, widely trusted brand
- Kirkland Signature (Costco) – same formula, much cheaper
- Keeps or Hims – convenient subscription services with their own topical formulas
Oral:
- Requires a prescription – services like Hims, Keeps, or Ro make this easy to get online
- Generic oral minoxidil is inexpensive once prescribed
Key Trade-offs
| Topical | Oral | |
|---|---|---|
| Effectiveness | Good | Better |
| Side effects | Scalp irritation, greasiness | Water retention, body hair growth |
| Convenience | Messy application | Just a pill |
| Cost | $20–$30/month | Very cheap |
My Recommendation
- Start with topical (Kirkland is great value) if you want lower risk
- Try oral through Keeps or Hims if topical hasn't worked or you want stronger results
