Before having any kind of color applied to your hair, select a salon with a certified color professional. Not every hairdresser is an expert in color. Find a salon that specializes in color and ask about the qualifications of their staff. Usually a high end colorist will charge more, but it's worth it. Considering you are looking for something for the holidays, think of this as a gift to you.
In any case, it's certainly true that coloring your locks can change the way you look. It can revitalize things taking them from boring to fresh and new. Which is why so many of us have wholeheartedly embraced coloring our locks. You just want to make sure the change is for the better.
