Oh yeah, I am optimistic about this too, but I wish some one would just TRY IT ALREADY. It doesn't even have to be Christiano or Jahoda. It can be any doctor or dermatologist. A doctor from Yale named Brett King tried this in oral form on some one with AA and he regrew a full head of hair, after I believe more than 20 years of having no hair. There is no reason why a similar thing cannot be done with Androgenetic Alopecia in a topical form. And that is what frustrates a lot of us on here. All of this stuff gets tried for AA but never for Androgenetic Alopecia. I am sure it would not be hard at all for a doctor or researcher to find at least one person with Androgenetic Alopecia who has the financial means and the motivation to try this stuff in a topical form.
