Propecia (finasteride): What It Does, How to Use It, and Smart Buying Tips

Propecia is a prescription medicine — generic name finasteride — used to treat male pattern hair loss. It lowers DHT, the hormone that shrinks hair follicles. Most men take one 1 mg tablet once a day. You won't see changes overnight: expect three to six months for early results and up to a year for clearer improvement.

Stopping DHT can halt hair loss and help some hairs grow back. Results vary by person and are best on the crown and mid-scalp. If you stop treatment, any benefit usually fades within a year. Keep photos every month to track progress — side-by-side pictures show small changes you might miss day-to-day.

How Propecia works and what to expect

Finasteride blocks the enzyme 5‑alpha‑reductase so less testosterone becomes DHT. With lower DHT, miniaturized follicles can recover and produce thicker hairs over time. Typical timeline: little or no change at first, slowing of shedding by month three to six, then gradual thickening up to month twelve. Don’t expect a full hairline restoration; Propecia is best at stopping loss and improving density.

Before you start, get a basic checkup and discuss PSA testing with your doctor — finasteride can lower PSA readings. Mention other drugs you take and any plans for fatherhood, since finasteride can affect sperm in some men. If you have liver disease or take interacting medicines, your doctor will advise whether finasteride is safe for you.

Side effects, safety, and buying tips

Most men tolerate Propecia, but some report lowered libido, erectile issues, or changes in ejaculation. These effects are uncommon and often reverse after stopping, though a few men report longer symptoms. Mood changes like depression have been noted; contact your doctor if you notice new mood or sexual problems. Keep follow-up visits to review benefits and side effects.

Combining Propecia with topical minoxidil often gives better results than either alone — they work differently and can complement each other. If you miss a dose, take it when you remember but don’t double up. Women who are pregnant or may become pregnant must not handle crushed or broken tablets — finasteride can harm a male fetus. Store tablets in a cool, dry place and keep them away from children.

Propecia is prescription-only. Avoid sites that skip prescriptions or sell at unreal prices. Choose licensed pharmacies with clear contact info, visible reviews, and secure checkout. In Canada, generic finasteride is common and usually cheaper than brand-name Propecia. Check pill strength — 1 mg is the hair-loss dose — and save prescription records and packaging in case you need batch info or a pharmacy contact.

If cost is an issue, ask your doctor about assistance programs or generic options. Give Propecia at least six months of daily use before deciding if it helps — patience matters. Talk openly with your provider about goals, side effects, and other treatments like transplants or laser therapy so you pick the safest plan that fits your life.
