Thank you all! LOL STEVE! I'm laughing my head off here. I'm only 29 and have always had VERY thick hair so it was rather sad for me lol. Glad to know it's not just Atkins and it can happen with any type of dieting. I'm going to pick up some biotin and see what happens. I wish I lost it evenly and it wouldn't be so noticable, but no, it's on the back of my head and I have almost black hair so I have this big huge white spot lol- about the size of a silver dollar. Now I can't tease dh- he shaves his head so nobody knows that at almost 30 he's going bald lol. He suggested me shaving mine. Ummm, no, not yet lol.
