For about a year I have been gradually dying my hair darker. It has been black for about 3 months. It has faded some and my roots are growing in. I want to go back lighter but I'm not sure what the best method is. I'm not really sure what my natural color is, I've been dying it since high school, but from my roots, it's an ashy light brown. I would like to go back to a lighter brown with reddish tones. I used to use a brandy color that I would love to go back to. Any suggestions?
