From what I have read, castration stops hair loss however, castration will not regrow hair that has been lost. If this is true, why would Proscar grow any hair? It is my understanding Proscar blocks a percentage of DHT, which leads to the effectiveness of the product. If someone has been castrated there is o% DHT and still no hair regrowth? Also if DHT causes hair loss why is Propecia effective on the vertex of the scalp and not the temples.
There is a wide audience of young men (over a million) who have taken Propecia and we know that in the very young man with active miniaturization, the process may be reversed. This occurs mostly in young men in their 20s. I would guess that if we castrated 1 million men who are balding in their 20s, that the incidence of regrowth would be higher than those on Propecia alone, but I am not recommending castration as this is only an intellectual exercise.
When a hair is dying (miniaturized hairs fall in this category), like a dying person, they have a chance of being fixed or cured because they are not dead yet. When a hair has completely disappeared, it has gone through apoptosis, which means that the hair growth center is dead… and we all know that you can’t raise the dead. This applies to hair when the head is slick bald in any area impacted where there is no miniaturized hairs.
