I recently wanted to dye my hair back to its natural color which is dark brown. So, I bought a dark brown colour and now my hair is almost black! The color matches perfect to my natural roots but the father I go down my hair the darker it gets. My question is how can I lighten my hair so it looks a little more like my natural color? And should I use the color zap to strip out the color? If so, what color will it come out looking like? PLEASE HELP!!
