I want to darken my hair?

Oh my gosh. I've had blond hair my whole life and i just dyed it light brown. I used Loreal Healthy Look Creme Gloss Color in Medium Brown ( Number 6 ). I loved it because it didn't use ammonia, so it didn't smell, and it even came with a conditioner to use once a week that keeps the shine the original hair dye gave you! Just be careful that your a natural blond and make sure you have a way to make your blond eyebrows work with brown hair!
