My hair is thin on top. I sort of have a bald spot on top of my head. It's been like that for a long time. I'm not sure what caused it to happen. I have gotten many hair treatments done in the past, so that might've caused some hair loss.

Anyways, does that hair treatment (forgot what's it's called, minoxil or something like that) work on women? It's kind of expensive, and I don't want to waste money on anything that doesn't work. Does Nioxin work too?

In the meantime, I use colored fiber powder to fill in the bald spots. It covers the semi bald spot well, but it does smear on my face and hands, so I can't touch my hair when I wear it. I have also tried vitamins for hair, skin, and nails, but that doesn't work either. And my diet is usually good. Is there anything I can do to stop my hair from thinning at the top?
