Mixing two different hair colors?

-The beauty supply store that I went to was out of the color i usually get, so I got two boxes of at home hair dye (the nice and easy foam) and I was going to put half of each bottle of color in the developer bottle. Will this work? The colors were Medium Golden Brown and Soft Black. Will it be black?you should try a really small amount first, thats the only way you麓ll know
Probably. I wouldn't mix them tho. Who knows what'll happen!
