Finasteride Results at 6 Months

Bottom line: At 6 months, clinical trial data begin to show meaningful divergence between finasteride and placebo. Most men will see stabilization rather than regrowth at this stage. Some will notice visible improvement; others will not yet see a cosmetic difference even if the drug is working.

Hair Count Data at Month 6

Group	Mean hair count change (vertex, 1 cm² target area)
Finasteride 1 mg	+4–9 hairs vs. baseline (1998 Propecia trials)
Placebo	−7–13 hairs vs. baseline
Net advantage finasteride vs. placebo	~14–18 hairs/cm²

These hair count differences, while statistically significant, may not yet be cosmetically visible to the patient or observer. Visible results typically require sustained treatment through month 12 and beyond.

What “No Visible Change” at 6 Months Means

If you do not see cosmetic improvement at 6 months, this does not mean the drug is not working. Stabilization (no further loss) is the primary benefit and may not be visually obvious unless you compare photographs. Standardized scalp photography taken at baseline and 6 months is the most reliable way to detect subtle changes.
