According to the theory, pressure on the hair follicles created by the weight of the scalp is the cause of AGA. Total weight of the skin, subcutaneous connective tissue, and galea are operative. With sandwiched fat tissue and fibrous connections between the skin and galea, all of these components of the scalp form a combined structure that sits on the cranial bones much like a separate structure movable on the cranial bones due to the intervening loose areolar tissue. Hair follicles are compressed by the skin against the calvarial bones. This theory is uniquely capable of explaining all related phenomena and paradoxes.
