PHOTOS: Celebrities who have dyed their hair red

At the What's Trending Launch StopBullying Campaign in Los Angeles Thursday, the Prom Night actress rocked her recent, red-hot hair makeover, which she originally debuted in New Orleans September 30.

Cunningham shares a few warnings, though: "Darker skin tones can look unnatural with this hue," says the pro, who also advises against hot-oil treatments.
