The first time scientists were able to grow artificial hair follicles from stem cells was in 2010. Scientists at the Berlin Technical University in Germany took animal cells and created follicles by using them. As a result, they produced follicles "thinner than normal", but they were confident they could develop the right method of cloning hair from human stem cells by 2011. They estimated that the therapy would be publicly available by 2015 as they were already preparing for the clinical trials. Scientists working on the project said if the treatment was finished, it would mean a cure for approximately 80 percent of those who suffer from hair loss.
The university was working together with Intercytex and several other research teams, but they encountered several problems. One of them was that the multiplication process was not efficient enough. They were only able to clone one or two follicles from an extracted hair but for the process to be efficient this number should have been around 1000. There was no indication that researchers were able to overcome this obstacle.
