Frequently asked

How long does finasteride take to work?

Slowing of shedding for most patients by month 3. Visible improvement in 60–70% of patients by month 6–12. Document with photographs every 6 months — gradual improvement is hard to perceive day-to-day.

What happens if you stop taking finasteride?

Benefit reverses 6–12 months after stopping. Hair count returns to where it would have been without the medication — sometimes shedding accelerates briefly during the transition.

Are finasteride sexual side effects permanent?

1–5% of patients experience sexual side effects (decreased libido, ED, ejaculatory issues). Most resolve when the medication is stopped. A small subset reports persistent symptoms (post-finasteride syndrome) — disputed in mainstream literature, recognized by patient advocacy. Discuss the risk-benefit before starting.

Topical finasteride vs. oral — which is better?

Topical compounded finasteride reduces systemic absorption and may decrease side-effect risk. Growing evidence base, but not FDA-approved. Oral has stronger long-term data. Many specialists offer both and let patients choose.

Can women take finasteride for hair loss?

Off-label use of finasteride for female pattern hair loss is increasing, particularly in postmenopausal women. Pregnant or potentially pregnant women must not take or even handle crushed finasteride — risk of birth defects in male fetuses.
