I forgot to say that if you decide to keep it, try slightly different shades of make up, this can make a huge difference. (Or try wearing some make-up if you don't normally.) The same with clothes, all yours will be in a blonde palette, now you are brunette different colours will suit you. Also, have you tried darkening your eyebrows to match your new hair? (I suggest make up not dye!) This can also make a huge difference.
