The most efficient follicular regenerating unit and the smallest follicular regenerating unit: potential treatments for hair loss.
Hair loss affects many people, especially adult males. An effective treatment is hair transplantation which involves harvesting hair grafts from a donor site and relocating them to a bald site. However, this traditional method, equivalent to one-to-one transplantation, simply redistributes hair rather than increases the number of existing hairs. Although hair transplantation is actually the transplantation of hair follicle (HF), it has been confirmed that whole HFs could be reformed from parts of HFs containing different constituents, implying the existence of more efficient and smaller HF regenerating units in a whole HF. Thus we hypothesize that the most efficient follicular regenerating unit (EFRU) and the smallest follicular regenerating unit (SFRU) could be found in whole HFs. As a result, the one-to-many hair transplantation would be achieved in clinic. One-to-many means to double or triple the number of hairs. In order to test and verify the hypothesis, we design a method called hair follicle micro-dissection (HFM) which aims to help find the regenerating units and increase the number of hair for transplantation. The postulation may provide a more mature and realistic treatment for hair loss if it proved to be practical.
