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.
Thinning hair? Did you know you can make it appear thicker by the strategic use of color? By that I mean if you color your root line to deal with any regrowth you're also making the roots look a bit darker. Not only does this touch up your color it will also create the illusion of thicker hair. That's because roots that are a bit darker make your hair appear to be fuller and more dimensional.
