Early androgenetic alopecia in men considered phenotypic equivalent of PCOS in women
Men with early androgenic alopecia, or patterned hair loss before age 30, could be considered phenotypic equivalents to women with polycystic ovarian syndrome and may have the same health risks, according to study results recently published in JAMA Dermatology.
The researchers conducted a case-control study of 57 men aged 19 to 30 years (mean age, 24.7 years) with androgenic alopecia who presented between Jan. 1, 2014, and March 31, 2015 to a tertiary care government hospital in New Delhi, India. Read more

Researchers conducted a propensity-matched retrospective analysis of patients in the Partners Healthcare Research Patient Data Repository between Jan. 1, 2000 and Jan. 1, 2010, at Brigham and Women’s Hospital and Massachusetts General Hospital in Boston. Read more

Researchers in Turkey studied 32 patients (19 men, mean age, 24.22 years) with alopecia areata including the scalp. The patients had a median disease duration of 36 months, and were refractory to at least two different convention alopecia areata treatments. Read more
Platelet-rich plasma shows positive effect on androgenetic alopecia
Patients who received a half-head treatment of platelet-rich plasma to treat androgenetic alopecia showed a clinical benefit at 6-month follow-up, according to recent research.
“This clinical research provides support that the application of [platelet-rich plasma] may have a therapeutic effect on [androgenetic alopecia] and can be used as a safe complementary treatment option,” Rubina Alves, MD, from the department of dermatology at the Universitat Internacional de Catalunya in Barcelona, Spain and colleagues wrote in their study.
