If you have male pattern hair loss (androgenetic alopecia), finasteride is usually the better first choice for slowing or stopping progression, while minoxidil is better for boosting visible regrowth. Comparative studies found finasteride to be more effective than topical minoxidil monotherapy overall.[2][1]
A practical way to choose is:
- Start with finasteride if your main goal is to prevent further loss, especially at the crown or mid-scalp.[2][12]
- Start with minoxidil if you want a topical option or are trying to avoid systemic hormone-related side effects; it can help regrow hair but does not address DHT-driven loss as directly.[12][4]
- Use both if you want the strongest overall results; studies consistently show combination therapy outperforms either alone.[5][8][11]
A few key points from the evidence:
- In one randomized comparative study, improvement was 80% with oral finasteride vs 52% with 5% topical minoxidil.[2]
- Another study found finasteride was more effective than minoxidil for male pattern hair loss overall.[2]
- Combination treatment produced better efficacy than monotherapy in multiple trials and meta-analyses.[5][8][9][11]
If you want the simplest decision rule: for men with typical androgenetic alopecia, start with finasteride unless you have a reason not to; add minoxidil if you want more regrowth or faster cosmetic improvement.[2][8][12]
Important caveats:
- Finasteride is prescription-only and can cause sexual side effects in a minority of users; it is generally not used in pregnancy and requires more caution in some women.[12][18]
- Minoxidil is often easier to start because it is topical and non-hormonal, but results usually take months and shedding can occur early in treatment.[7][12]
If you tell me your sex, age, pattern of loss, and whether you prefer topical vs oral treatment, I can suggest the more suitable starting option.
