How Do Hair Follicles Become DHT Sensitive?

According to what I read regarding Male pattern Baldness It is a problem of Hair Follicles being sensitive to DHT rather than excessive DHT. What does this really mean? How did I develop this condition? Is there any way to reverse this sensitivity? If not then why aren’t researchers and scientists working on it? Why is it so that DHT gets attached to my scalp follicles more than other parts...
