My son suffers from Alopcia Areata. All the US doctors wanted to do was flood his scalp with ever more powerful steroids. I put a stop to that. Then, after his sophomore year of HS, I sent him to China for treatment. He came back 3 months later with a completely full head of hair (and spoke Cantonese as well). I was just thinking a few days ago that there must be a way to market that (totally natural) treatment regimen in the US.
