Never use black market products. Hair restoration is in a constant state of innovation right now. However, black market means no oversight. A krokodil cook is still using a chemistry. Legitimate MDs would almost always keep their license over working with unnecessarily dangerous products. PRP + ACell, for instance, both encourages hair growth and retention for up to several years.
As for the article, seems interesting. Maybe it will lead to something.
