Although there have not been studies that have evaluated the results of Dutasteride when taken three times a week, there have been studies that have looked into lower doses of Dutasteride. In one [3], where patients were given either 0.02mg, 0.1mg, or 0.5 mg a day of Dutasteride, it was the 0.5mg dosage that significantly increased hair count and width after 24 weeks.
