TLDR More men have Androgenic Alopecia than women, it's often inherited, and stress can contribute to it.
The study, conducted 14 years ago, examined 432 patients with Androgenic Alopecia (AGA) over two years. The study found that there were 2.06 times more men (291 patients) than women (141 patients) with AGA. Most men were in their twenties (37.1%), while most women were in their forties (29.7%). The most common AGA type was Norwood class IIIv in men (41.2%) and Ludwig class I in women (61.7%). A family history of AGA was present in 75.2% of male patients and 73.6% of female patients. Co-morbidity disorders were found in 76.9% of male patients and 53.4% of female patients, with seborrheic dermatitis being the most common. Stress factors, primarily work tasks, were observed in 55.6% of male patients and 55.3% of female patients. Increased serum testosterone levels were found in 17.5% of male patients and 14.1% of female patients. The study concluded that the number of female AGA patients in their forties was increasing and that stress was associated with AGA in both male and female patients.
