stupid at home hair coloring

Now that your hair is medium red, light brown isn't an option, unless you strip the color out of your hair and start all anew. I don't recommend this though, because bleaching at home is risky and VERY damaging!

The best thing to do would be to go to a darker shade. Whether it be a dark reddish brown or brown with no red is up to you. Seeming that you already have red in your hair, I would try a rich, darker golden brown color. The red will show through a little.

Ash brown would try to dismiss the red tones in your hair, but it would probably end up looking a ratty grayish color. And even then, it wouldn't be able to totally get all the red out. You would just be stuck with multi-toned mousy colored hair.

So get something rich and dark. Get a level 2. Don't use permanent. It will dry it out too much.
