If you’re not sure of your classification, take a peek at your wardrobe to see what colors flatter you most. If they’re warm (yellow, tomato red), go for warm shades. But if they’re cool (lavender, royal blue), choose a neutral color. If you’re a mix? You can probably test out many colors, but seek a professional’s advice for best results. Finally, look at the instructions of the color kit. Most will list essential supplies, like a bottle applicator, comb, and hair clips. Lay everything out for easy access. And if your set doesn’t come with plastic gloves, make sure to buy some since you want your hair to be colored, not your fingers. Don’t forget that hair color also impacts your skin. Many people have adverse reactions to chemicals, which can cause a burning or irritating sensation. Annen suggests doing the same test to your skin, ensuring you won’t feel as if your head is on fire when you dye your hair. She suggests applying a dot of dye to your inner elbow to see how your skin responds. If testing out your color isn’t an option, look for a hair color that closely resembles your natural color, or choose a product like Clairol Natural Instincts ($8; ulta.com), an ammonia-free formula that enhances color and shine, but will not lighten hair.

Fitzsimons suggests Rita Hazan Root Concealer Touch-Up Spray ($35; sephora.com), which comes in a wide variety of shades and colors that complement most tones and hues.
