I'll start off. My hair is very long, it's about two inches away from my butt ( hopefully it will be at my butt by my birthday in July! ). My hair is ( naturally ) black, thanks to my Dad.
I did put coppery-colored highlights in my hair once several years ago, they are finally grown out, so you can't really see them. That is the only time I put highlights or any kind of dye in my hair. I like my natural hair color and almost everyone else loves it too.
My hair is pretty thick, especially for how long it is. It hasn't been cut since January of 2003, so a little over a year. I switch on and off products. Right now I'm using Suave because, well, it's cheap and smells pretty. I go through about one bottle of shampoo every 3-5 weeks, so it can get expensive. I do like Garnier Sleek and Shine.
I adore my hair, I wouldn't shave my head for a million dollars, I'm not kidding.
