I have light ash brown hair and have been professionally highlighting it for years. I decided to go brown and used a dark ash brown hair color on my own. It turned my hair black. If I use a color remover can I go with any color or will blonde colors tend to go red?

If you want to go lighter or blonde it would be best to lighten your hair bleach and then apply the desired color. Anything other than that will result in brassy red/orange shade.
