Dihydrotestosterone (DHT), a derivative of a hormone "testosterone". Under certain conditions, DHT wants those follicles dead. This simple action is at the root of many kinds of hair loss such as Androgenetic alopecia(commonly called female pattern baldness), Telogen Effluvium, Anagen Effluvium, and Traction alopecia.
Women have a minute quantity of testosterone, but even a lower level can cause DHT- triggered hair loss in women.
So, you need to understand that "testosterone causes the female baldness", it converts to DHT with the aid of the enzyme Type II 5-alpha reductase, which is held in a hair follicle's oil glands. In short, DHT is the main reason behind hair loss in women.
From a genetic predisposition to birth control pills to menopause, Hormones and hormonal changes are the leading causes.
Birth Control Use
Birth control pills contain artificial progestins that act like male hormones, known to shrink and damage the hair follicle. An overabundance of male hormones in women could potentially contribute to insulin resistance as well.
Low Thyroid Function
This is indicated especially if hair loss is accompanied by fatigue, unexplained weight gain, aching joints, constipation, dry skin, feeling cold all the time, poor sleep, etc. Hair follicles are sensitive to thyroid hormones.
