How can I be sure the hair color I choose will be flattering to my skin tone?

First, determine your skin tone. Do you have warm (red) or cool (blue) undertones? If you don't know, try this test: try on a white T-shirt, then a beige T-shirt. If the white T-shirt suits your skin color best, your skin has cool undertones. If the beige is more flattering, your skin has warm undertones. Choose hair color with tones compatible with your skin tone. Warm tones are red, gold and auburn. Cool tones are plum, ash and blue. Make a subtle change first. You can always be more daring! For best results, consult your stylist.
