What to expect
How long until finasteride works?
Reviewed by the FaroRx clinical team · Updated September 2026
The short answer
Finasteride lowers scalp DHT within days, but visible change takes time: shedding often slows by month three, new growth becomes noticeable around month six, and peak results appear at twelve to eighteen months. An increase in shedding during the first 4–8 weeks is normal and usually a sign the hair cycle is resetting.
Month by month
| Timeframe | What you should see |
|---|---|
| Week 1–8 | Possible temporary shed; no visible change yet |
| Month 3 | Shedding slows; hair feels less fragile |
| Month 6 | Visible density improvement, especially at the crown |
| Month 12–18 | Peak result; maintenance from here |
How to know it is working
- Take a fixed monthly photo in the same light and angle — memory is unreliable.
- Count hairs in the shower drain over a week rather than judging one day.
- Judge at month six, not month two.
- Consistency beats dose: a missed week matters more than the exact time of day.

Common questions
Why is my hair falling out more on finasteride?
An initial shed in the first 4–8 weeks is common as follicles synchronise into a new growth phase. It usually settles by month three.
Is 3 months enough to judge finasteride?
No. Month six is the fair checkpoint, and results keep improving to 12–18 months.
Does adding minoxidil speed it up?
It tends to bring visible regrowth forward, since minoxidil works on a different part of the cycle.
