Question 1

How does finasteride differ from minoxidil?

Accepted Answer

Finasteride reduces DHT to stop follicular miniaturisation, while minoxidil is a vasodilator stimulating hair growth directly.

Question 2

Does finasteride affect testosterone levels?

Accepted Answer

Serum testosterone may increase by 10‑20% because less is converted to DHT. This remains within normal range.

Question 3

How quickly does DHT drop after starting finasteride?

Accepted Answer

Serum DHT falls by about 70% within 24‑48 hours of the first dose. Scalp DHT reduction takes a few more days.

Question 4

Why does finasteride not affect body hair?

Accepted Answer

Body hair growth is driven more by testosterone than DHT. Finasteride leaves testosterone levels unchanged.

Question 5

Can finasteride be used indefinitely?

Accepted Answer

Yes, finasteride is safe for long‑term use. Benefits continue as long as you take it; stopping will reverse effects.
