Found an interesting article proposing a differing theory for hair loss on the scalp: excessive pressure on the hair follicle due to a loss of subcutaneous fat, which normally provides cushoning from the weight of the scalp. It also suggests that the buildup of DHT is the body trying to help the hair follicle grow under these tougher conditions, not the cause for the hair loss itself.
This info could be a good addition to the Hair Loss Reversal audios.
