Well, as someone with really fine hair, when my hair was in layers, my longest layer looked sickly because it didn't have any other hair to back it up. I am still trying to grow my hair back to even. Every layer that I got rid of made my hair look thicker and better. If ever I get layers again, they will be a few in the front to frame my face which I already have naturally right now because I am growing out my bangs.
