Why did Jessica Simpson needed edgy hairstyle?

Los Angeles: Singer-turned-fashion designer Jessica Simpson recently brightened her blonde locks.

Her hair colourist Rita Hazan says the change in colour was required to complement her new hairdo, which is a few inches shorter than her usual length.

"Now that she cut her hair, she needed a cool and edgy colour," Hazan was quoted by usmagazine.com as saying.

"I made it a cool champagne blonde - very light, almost white, but with depth and dimension," she added.
