I really need some help. My sister hosted one of those "beauty makeover" parties and wanting to support her I attended and ended up having my hair colored by a natural dye which I think was pretty much brown henna. I hate the results. My hair is really dry and uncontrollable now and the gray I have isn't covered much at all, just looks a tad bit darker, but it isn't fooling anyone. Can I use ecocolors over this bad hair color, and if so, what color should I use to get back to my medium to dark brown as well as covering the gray? I appreciate your help and thank you in advance.
