Answer: It’s all hormonal. Male pattern baldness is genetic and it’s due to testosterone, which is why it can sometimes start in puberty. The testosterone causes the hair to grow differently and thus is falls out. Women do secrete some testosterone, but they also secrete female hormones, progesterone and oestrogen, which trump the testosterone, thus women don’t go bald. That is, until the menopause, when sometimes you can see balding women. That’s why you also sometimes see elderly women with facial hair.
