i eat soy on a daily basis. Soy burgers, soy chicken, soy milk, soy everything. I'm a vegetarian. none of this soy seems to be doing jack for my hairline.
i'm getting awesome results with minoxidil on my hairline using twice a day. I've only been using for 1 and a half months, and i can see my old hairline coming back in. No pigmentation, but there are hairs there now, and that gives me a ton of confidence.
