For darker-haired girls who have always wanted to try out something more vibrant, rich auburn is a happy medium between red hair color and brunette hair color. Coco Rocha, Julia Roberts and Debra Messing are our auburn-haired idols.

Who Can Pull It Off: If you're on the pale side, auburn hair color will complement your skin tone beautifully, but if you have medium to dark skin tones you're better off with a violet-toned red hair color.

What to Ask For: "The biggest mistake any redhead can make is over-highlighting," says de Souza. Be clear about how monochromatic or multi-faceted you want the color. This is up to the individual's preferences, but remember, color that's too uniform can tend to look flat.

Beware Of: Make sure to stay away from dark, eggplant hues, which can make your skin look yellow, and wine or burgundy shades, which can wash you out.

Jessica Chastain has always been a style icon, but right now her copper hair color makes her a major trendsetter in the beauty department as well. This bright color adds instant personality to your look.

Who Can Pull It Off: Fair skin tones look best with copper hair color. The deeper your skin tone, the richer you want your copper tone to be.

What to Ask For: Copper hair color is extremely easy to manipulate, so if you don't get the right tone the first time around (i.e. it looks too warm for your pale skin), just ask for the color to be brightened. "You can't be afraid to speak up," says Petroff. "We don't get offended. We want you to get the color you want."

Beware Of: While over-washing your hair and overexposure to sun can certainly fade red hair colors, Petroff says wind and oxygen are actually the number one cause behind fading hair color. To tide you over between treatments, try a color gloss like John Frieda Colour Refreshing Gloss and use sulfate- and silicone-free shampoos.
