people always ask me where I get my hair done, and are generally shocked when I say the L'Oreal box. haha.
I say give it a go! buy a hair dye that promises to bring out natural highlights as well to give you a more multi dimensional color, which will look great on curly hair.
You can't tell in the picture.. what color is your hair now? I think you should go auburn or a reddish bc you have such pale skin. I'm afraid dark brown would wash you out.
but then again I'm a blonde and I don't know a ton about dark hair! Let us know what you decide!
