Hair loss is now linked to metabolism, according to research from University of California, Los Angeles. The study finds that the metabolism in the stem cells embedded in hair follicles is different from surrounding cells. When scientists altered the metabolic pathway in mice stem cells, they could either halt or proliferate hair growth. The researchers are now testing a duo of drugs that targets an enzyme called lactate dehydrogenase – that could be responsible for some forms of hair loss – to try and prompt hair to grow. The research is still in preclinical stages, but the researchers hope to raise enough funds to move this to human testing. Source
