Finasteride suppresses DHT while you take it. Stop, and DHT returns to its previous level within days to weeks, and the process it drives resumes. Hair that was being maintained by the medicine is gradually lost, and within roughly six to twelve months most people return to where they would have been had they never treated.
You do not lose more than you would have. You rejoin the trajectory you were on.
A Realistic Timeline
- Days to weeks: DHT levels normalise
- 2 to 3 months: increased shedding often becomes noticeable
- 6 months: visible thinning in the areas that had been maintained
- 12 months: generally back to the untreated baseline
Individual variation is wide, and how long you were treated changes what there is to lose.
Reasons People Stop
Side effects
This is the most important category and should not be second-guessed. If you develop depression or suicidal thoughts, MHRA advice is unambiguous: stop taking finasteride 1mg and contact a doctor as soon as possible. Sexual side effects are a legitimate reason to stop and should be discussed with a prescriber rather than endured.
Planning a pregnancy
Finasteride does not require men to stop before conception on the basis of current evidence, but it is a common reason people re-evaluate. What genuinely matters is that women who are or may become pregnant must not handle crushed or broken tablets. Discuss it rather than assuming either way.
Cost or effort
Indefinite treatment is an indefinite cost and an indefinite habit. Deciding it is not worth it is reasonable, and better made deliberately than by running out and not reordering.
It stopped working
Worth examining before stopping. Finasteride slows loss more than it regrows hair, so "no improvement" may still mean it is doing its job. Photographs beat impressions here.
Can You Stop and Restart?
Yes, and it will work again — but the hair lost in the gap does not necessarily come back. Follicles that have miniaturised past a certain point do not recover. Intermittent use is the worst of both worlds: the side-effect exposure without stable benefit.
Do You Need to Taper?
There is no established need to taper finasteride, and no evidence that tapering prevents the return of hair loss. Some people reduce gradually when stopping because of side effects; that is a conversation with a prescriber, not a standard protocol.
The Persistent Side Effects Question
The MHRA states that sexual side effects may persist after stopping. How often that happens is not well quantified. If you have stopped and symptoms have not resolved, see a doctor — this deserves proper assessment rather than online reading, and there may be other contributing factors that are treatable.
The Decision Underneath
Starting finasteride is really a decision to take a medicine indefinitely for a cosmetic outcome. That is a legitimate choice, and so is stopping. What is worth avoiding is the drift — stopping without deciding to, restarting without a plan, and getting the exposure without the benefit.
