This is a big topic, so I’ll do my best to give you the short version. We’ll start with this: how do you figure out what color your hair should be and what will it take for your colorist to get you there? Start with these questions: How much do I want to spend? How often will I get my hair retouched? Do I currently cover my hair for grey coverage? What texture is my hair? How realistic is my goal and am I willing to keep spending the time and money it may take to maintain it?
