Snippet from the article:
Daily treatments of dutasteride 0.5 mg were more effective than finasteride 1 mg daily or placebo in increasing hair count and width in men with androgenetic alopecia, according to recent study results.
Researchers randomly assigned 917 men, aged 25 to 50 years with androgenetic alopecia, to dutasteride at 0.02 mg/day (n=185), 0.1 mg/day (n=188), or 0.5 mg/day (n=184), finasteride at 1 mg/day (n=179) or placebo (n=181) for 24 weeks. Hair count in a 2.54-cm diameter was the primary endpoint, while hair count (1.13-cm diameter) and width, photographic assessments by investigators and panel, change in stage and health outcomes also were assessed.
Researchers observed that in patients assigned dutasteride, hair count and width increased dose-dependently. At week 24, dutasteride 0.5 mg increased hair count (P=.003) and width (P=.004) in a 2.54-cm diameter and improved hair growth (frontal view, panel photographic assessment; P=.002) compared with finasteride and placebo (P<.001, all).[/bq] Read the rest — Dutasteride superior to finasteride in restoring hair in male alopecia patients

There are still the looming questions about sterility, which have not been addressed in this study. Dutasteride may have more such side effects, as have been reported with the higher dosage for treating prostate issues. Either way, if a doctor prescribes this off-label for treating hair loss, that is a decision between physician and patient.
