This article is saying the same thing we have been hearing for months. That is, they can initially grow hair outside the body but it stops growing because they have not been able to perfectly reproduce (impossible imo) the environment of the body inside test tubes in order to grow those cells.
So from my understanding they are getting better at growing hair in vitro which is outside the body (in test tubes or whatever medium, they use to nourish the cells) , but it is nowhere near being optimized enough so that they are consistently growing complete cells that will grow healthy dark thick hair to be transplanted onto your head.
In conclusion, a hair loss cure coming from growing / cloning cells that grows hair is still years away.
Hehe I take it you haven't been very active this year ? This was the breakthrough news of 2013. Unfortunately the current Dp cell expension method is not good enough to retain all gene expression, only 22% was left, so although this was enough to generate hair, the hair was not cosmetically useful (thin, colour missing etc). It needs to be optimized before clinical trials can start. And nobody can predict when that will happen ...
