What should you know about the Propecia hair pill?

Finasteride lowers the effect of dihydrotestosterone on susceptible follicles. In androgenetic alopecia, that can reduce follicle miniaturisation and help maintain existing hair; some follicles may produce thicker-looking strands over time. It does not work as a universal remedy for shedding, and it cannot replace an examination when loss is sudden, patchy, painful, or associated with scalp changes.

The same name can be used casually for products that are not the prescribed medicine. Confirm the active ingredient and instructions with a clinician and pharmacist before taking anything.

Follow the prescribed schedule and take only your own medicine. If you miss a dose, follow the supplied instructions rather than taking extra tablets. Keep photographs and note changes in shedding, density, mood, sexual function, and breast tissue. Tell the prescriber about other medicines, liver disease, allergies, and pregnancy potential in the household. Topical minoxidil may be discussed when it suits the diagnosis.

Speak with your prescriber about persistent sexual side effects, breast enlargement or tenderness, low mood, or troubling thoughts. Seek urgent assistance for hives with facial swelling, wheezing, or difficulty breathing. Promptly report new eyebrow loss, scalp inflammation, or sharply demarcated bald areas.

Ask whether your hair pattern fits the treatment, how to compare photographs, when to review progress, and whether another cause should be investigated. Clarify handling precautions, missed-dose instructions, and which symptoms require urgent attention.
