The role of oestrogens on the regulation of human hair growth is poorly understood. Using whole human scalp hair follicle organ culture, we have recently demonstrated, that human hair growth is inhibited by 17beta-oestradiol, but not by the biologically inactive isomer 17alpha-oestradiol. Using immunohistochemistry, we have also demonstrated the presence of both ERalpha and ERbeta in the pilosebaceous unit and the dermal papilla, a mesenchymal structure that controls the diffe...
