The full read
Five-year controlled data: ~90% of men maintained or improved hair counts versus 25% on placebo. Sexual side effects occur in a small minority (2–4% in trials) and typically resolve on discontinuation; discuss risks with a doctor rather than internet anecdotes in either direction. Prevention beats regrowth — starting early preserves far more hair than any later intervention recovers.
