Snippet from the article:

It turns out that when it comes to growing hair that’s stopped growing, and stopping hair from growing where people don’t want it, the same molecules in the human body are at play, according to a new study from the University of Pennsylvania School of Medicine.

Researchers writing in the journal Cell Stem Cell this month say that balding is caused by the protein inhibitor Dkk1, which stops the intracellular Wnt/β-catenin pathway from functioning properly. They further found that stem cells for dormant hair follicles are still maintained after balding begins. When Dkk1 is removed, the Wnt/β-catenin pathway resumes normal function, stem cells were activated, and hair growth is restored.

We are getting a better understanding of the balding process and potential solutions as described in this interesting article.
