Finasteride works by lowering scalp DHT, and the hair cycle is slow, so patience is essential. Most people notice less shedding first (around 3-4 months), then gradual thickening of existing hairs and some regrowth between 6 and 12 months. Maximum benefit is usually seen by 12-18 months. An early increase in shedding ('dread shed') in the first weeks can happen and isn't a bad sign.
Track it with monthly photos in the same light and angle rather than the mirror, which is unreliable. If you see no change at all by 12 months of consistent daily use, talk to a doctor about adding minoxidil or other options. Remember the benefit is maintenance — stopping reverses the gains over the following months.

FAQ
What if I see no results after 6 months?
Six months is still early for finasteride — judge it at 12 months. Less shedding is often the first sign before visible regrowth. If there's truly nothing by a year of daily use, ask a doctor about combining treatments.
Does finasteride work faster with minoxidil?
They work by different mechanisms and are often combined for a better result. Minoxidil may show visible change a little sooner, but both still need 6-12 months to judge properly.
