text: In 2012 scientists from the University of Pennsylvania School of Medicine published their own findings regarding hair cloning. During their investigation, they found that non-bald and bald scalps have the same number of stem cells, but the progenitor cell number was significantly depleted in the case of the latter. Based on this, they concluded that it is not the absence of the stem cells that are responsible for hair loss but the unsuccessful activation of said cells.
  The researchers continued their investigation and are looking for a way to convert regular stem cells into progenitor cells, which could mean they may be able to activate the natural generation of hair on a previously bald scalp.
