What's the state of the hair regrowth world?

[79BirdofPrey]

Hi all,

Last time I was here was probably two years ago. At that point PRP and Histogen seemed to be hot topics. There was also something about using stem cells to replicate hair molecules.

I took a quick look around. Histogen in Phase II testing? Does that mean the results have been positive?

I just wanted to ask what the overall state of the art was for hair regrowth. What's proving to be good? Have any sound numbers been released?

Thank you.
