April 2011 in “Rapid communications in mass spectrometry/RCM. Rapid communications in mass spectrometry” This study found that using hair steroid profiling, dutasteride treatment led to reduced dihydrotestosterone levels and DHT/testosterone ratio in patients with male-pattern baldness.
122 citations
,
November 2010 in “Journal of Dermatological Science” This study found that increased expression of type II 5α-reductase, androgen receptors, and Hic-5/ARA55 in dermal papilla cells upregulates androgen sensitivity, playing a key role in androgenetic alopecia pathogenesis.

215 citations
,
November 2006 in “Journal of The American Academy of Dermatology” This study found that dutasteride increased scalp hair growth in men with male pattern hair loss, particularly at a 2.5 mg dose, and was more effective than finasteride over 24 weeks.

,
December 2002 in “Molecular and Cellular Endocrinology” This study found that finasteride improves scalp hair growth in men with male pattern hair loss by reducing scalp dihydrotestosterone levels, but it did not benefit postmenopausal women with female pattern hair loss.
32 citations
,
August 1999 in “Journal of Investigative Dermatology” This study found that individuals with early onset extensive androgenetic alopecia have an elevated ratio of DHT to testosterone, but no significant genetic linkage to markers on chromosomes 2 or 5 was detected.
