DHT and Follicles That Are Transplanted

Dear Sir/Madam,
I would like to know how a hair follicle falls off. I was told that as DHT accmulates at the bottom of hair follicles hair falls off. This DHT is produmed by male harmones. Is this true? If this is the case even after hair transplantation DHT will be accumulating and it will cause the transplanted follicle to fall off. Then how is hair transplantation a permanent solution?

I think you have it wrong. DHT does accumulate in body tissues, but it has no hair loss impact unless there is a genetic defect in the hair follicles. The hair in the back and around the sides of the head have no genetic defect, so the DHT does not impact these follicles. The follicles are, for all intents and purposes, immune to DHT.
