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.

1. What does this really mean?

2. How did I develop this condition?

3. Is there any way to reverse this sensitivity?

4. If not then why aren’t researchers and scientists working on it?

5. Why is it so that DHT gets attached to my scalp follicles more than other parts of my body like my face?

6. Does DHT lead to bone growth?

Note: I’m losing hair and I have a receding hairline and I’m thinning on the top. I still don’t have a proper beard.

DHT is a trigger in people who have the genes for balding. Each hair on your head has a life cycle (usually 3 years) and it sheds and regrows over and over again, unless, it has a limit genetically set on how many cycles you get. Some men (in the balding areas) have limits on these cycles, so when that limit is hit, the hairs miniaturize and eventually fall out. Finasteride slows this process down and is the ONLY medication available that is known to work.
