Thin hair, would rogaine work?

[ericjo]

I think my hair was thin while I was in high school (6-7 years ago) but it wasn't this thin. I think that my hair is thinning extremely slow throughout the years, but I've came to notice it much more nowadays. My hairline is exactly the same (nothing moved) but just the top of my head is losing hair (I believe). What are my options? Does rogaine/minodoxil work? My hair is usually only noticeably thin when light above me, and it looks bad in the sun.

Thank you!
