Is it worth spending the money for salon color if you are not switching up your natural color? I have a few gray strands and I would like to color my hair. Nothing extreme...just close to my natural color which is dark brown. Going to the salon is so expensive I'm wondering if it's really worth having my color done there if I'm not really changing my color. I hear so much negative stuff about boxed color I'm kind of freaked out that I might damage my hair!!!
