One of the most common reasons men stop taking finasteride is unrealistic expectations about timing. Hair growth is a slow biological process, and finasteride needs time to lower DHT levels, halt miniaturisation, and allow follicles to recover.
The First 3 Months
During the first 1 to 3 months, many men notice no visible improvement. Some may even experience a temporary increase in shedding. This is normal — finasteride is shifting follicles from the resting (telogen) phase into the growth (anagen) phase, which can cause weaker hairs to shed before stronger ones replace them.
At this stage, finasteride is already reducing your DHT levels significantly. The biochemical changes are happening even though visible results have not yet appeared.
3 to 6 Months
Most men begin to see the first signs of improvement between months 3 and 6. This typically appears as:
- A noticeable reduction in daily hair shedding
- Hair feeling slightly thicker or denser
- Fine vellus hairs appearing in areas of thinning
Clinical trials confirm that measurable increases in hair count are typically detectable around this mark, though these early changes can be subtle.
6 to 12 Months
This is when most men see meaningful visible results. By 12 months, clinical data shows that approximately 65% of men experience some degree of regrowth, and over 80% show stabilisation of hair loss. The NHS and MHRA guidelines recommend giving finasteride at least 12 months before assessing effectiveness.
12 to 24 Months and Beyond
Finasteride continues to improve results for up to two years in many men. After this point, most men reach a plateau where their hair count stabilises. Continued daily use is necessary to maintain the benefits — stopping finasteride typically results in resumed hair loss within 6 to 12 months as DHT levels return to normal.
How to Track Your Progress
Taking progress photos every 3 months under consistent lighting is the best way to objectively assess whether finasteride is working. Day-to-day changes are too gradual to perceive in the mirror. If you are concerned about your progress, discuss your results with your prescriber or a GPhC-registered pharmacist who can offer guidance on next steps.
