Effect of dutasteride 0.5 mg/d in men with androgenetic alopecia recalcitrant to finasteride
November 2014
in “International Journal of Dermatology”
TLDR Dutasteride helps hair growth in those unresponsive to finasteride, but may cause more sexual dysfunction.
The study found that dutasteride at a dose of 0.5 mg/d could be an alternative therapeutic option for patients with androgenetic alopecia (AGA) who did not respond to finasteride. Hair density and thickness significantly increased by 10.3% and 18.9%, respectively, in phototrichogram assessment. However, the incidence of dutasteride-related sexual dysfunction is reported to be higher than with finasteride, so further research is required to identify the incidence of dutasteride-related sexual dysfunction and the timing to switch to dutasteride if there was no clinical improvement.
