Don't be overwhelmed by endless drugstore hair color aisles. "Save yourself a lot of time and money by first ruling out what won't work for you," advises Pastor. If you're changing your color more than two to three shades, trying lowlights, adding highlights to red or brunette hair, or have extremely damaged strands, leave the heavy lifting to the pros. Other tips to keep in mind: Permanent dyes are best for covering grays, but sheer glosses are ideal for brightening your shade or adding a new tintblondes can go strawberry blonde with a red gloss; brunettes can warm up with a blonde gloss.
MC TIP: Manage your expectations and focus on color swatches, not hair models, when selecting a shade.
