Whatever you do, DONT use rogaine. I have the same problem with thinning only in that area, and I tried rogaine and actually lost much more hair...it was devastating for me really! Then I find out that you lose good surrounding hairs before you gain growth, and of course have to stay on these horrible chemicals the rest of your life or you lose what you have gained. The other thing is that I started growing horrible hairs in weird locations, like the back of my neck...I looked like a gorilla really. I had to pluck them all out.
