Tadaaaa! Bye bye blonde, hello Brownie deliciousness! I absolutley love my new hair color and to get it I (my sister) did the base with the Light brown 500 and added a thin layer with Chocolate truffle 515 (which is slightly copper toned) on top. The end result is a medium brown with a hint of mahogny shimmer! I think I just saved myself from a well needed haircut because after the treatment it feels like I've already had one.
