What is pattern hair loss?
Pattern baldness is also called androgenetic alopecia because it tends to happen in response to the male sex hormones (androgens). Genetics also plays a part in pattern baldness with it being passed on variably within families. Women also produce androgens, but in different ways, so the pattern of hair loss is different. Male pattern baldness usually starts with receding hair around the temples, followed by balding on top of the scalp. Hair often remains at the back and sides. Female pattern hair loss usually only causes thinning of hair on the top of the head.
