Convinced you should go red, too? Colleen Flaherty , colorist at Spoke & Weal salon in New York , says that this is something you need to do research for. Go through your Instagram, consult your colorist, and find photos with hair colors you're inspired by. Flaherty says that when she meets with a client who wants to dye their hair red, she asks them how long they've wanted to go red and what sparked the change. "I also give them real expectations on what their color can realistically turn out to be," Flaherty explains. "Red hair tends to fade quickly based on how much you wash and how much you heat style. I make sure they understand that and let them know they should come in for a gloss to refresh the tone in-between color appointments."
