Consolidated Summary and background and Summary

Finasteride is an oral prescription medicine most commonly known by the brand name Propecia when used for male pattern hair loss. It works by inhibiting the enzyme 5-alpha-reductase, reducing the conversion of testosterone to dihydrotestosterone (DHT). Lower DHT concentrations near scalp hair follicles can slow hair thinning and, in some men, lead to partial regrowth.

Brief facts:

  • Active drug: finasteride
  • Main hair indication: androgenetic alopecia in adult men (usually for those 18 and older)
  • Typical tablet strengths: 1 mg for hair loss; 5 mg available and licensed for benign prostatic hyperplasia (BPH)

Permissible Uses

In the United States, finasteride 1 mg tablets are approved for the treatment of male pattern hair loss in adult men. Continuous daily therapy is necessary to maintain benefits; stopping the drug typically results in gradual loss of any hair gains within several months.

The 5 mg formulation is approved for BPH, a separate indication. While 5-alpha-reductase inhibitors may affect prostate disease markers, they are not a sole treatment for prostate cancer. Discuss prostate screening and management in the presence of your clinician.

  • Take one 1 mg tablet by mouth once each day for adult men.
  • Tablets may be swallowed with water and taken with or without food.
  • Avoid breaking, crushing, or handling damaged tablets; contact with exposed tablet material could be harmful to a pregnant person.
  • Clinical effect is usually assessed after several months; many clinicians evaluate response at 3 to 6 months or later.

  • Dutasteride - another 5-alpha-reductase inhibitor sometimes used off-label for hair loss; it inhibits additional enzyme subtypes and has a longer half-life than finasteride.
  • Low-dose oral minoxidil - an off-label option used by some specialists for diffuse thinning when topical therapy is inadequate.
  • Procedural options such as hair transplantation, platelet-rich plasma (PRP) injections, and low-level laser therapy devices.
  • Cosmetic approaches like hair fibers, styling, or concealers to improve appearance without medication.
