The root cause for hair loss problem on the human scalp has not been fully understood. It is the first time for this work to investigate the softness and thickness of the distinct localized regions in both non-bald and bald scalps on their effects to the natural hair regrowth for different people. The geometrical shape of each individual human head deviated from the skull bones was also compared and studied. In non-bald scalp regions, 1) each region has a uniform skin thickness and it is thin; 2) the skin is soft; 3) the human head is in flat shape. As for bald scalp regions, 1) each scalp region has a non-uniform skin thickness and it is thick; 2) the skin is hard; 3) the human head is in dome shape. A flat/ close shape between the scalp and the skull bones, a thin skin thickness and a soft skin are demonstrated to the the prerequisite conditions for natural hair regrowth. A good control of these key parameters by detumescence therapy on human scalp is found to be an effective and efficient approach for natural hair regrowth.
