Absolutely! Please do. We love seeing what mixing our shades will do, or if you have multi-colored hair, all you need to do is section! When trying out multiple colors, we recommend staying within similar color families that are next to each other on the color wheel. For instance, pink goes well with red or purple - but mixing pink with green or teal may end in some funky brown or grey results, since they cancel each other out as opposites on the color wheel.
