Key takeaways
- Finasteride is an oral prescription medicine; topical minoxidil is applied to the scalp and is commonly sold without a prescription.
- Eligibility, expected use, contraindications, pregnancy-related handling precautions, and side effects differ substantially.
- Hair loss has multiple causes, so a diagnosis and realistic treatment plan matter before comparing products.
