There have been a large number of celebrities like Vanessa Hudgens, Dakota Fanning, Hillary Duff, Jessica Biel, Drew Barrymore, and Kate Beckinsale who have sported the ombre hair look. The newest celeb to join the clan is Jessica Alba.

Alba, who is currently shooting for the sequel of 'Sin City', tweeted a picture of herself in her natural brunette hair saying, “Bye bye brown hair.” Later, she tweeted another picture showing off her ombre hair, which is brown on top and blonde in the bottom.

The site BuyHair.co.uk has seen a huge rise in the sale of ombre hair extensions, according to a press release. The site also offers clip-on hair extensions in two-toned colors so that one can achieve the look without having to actually dye their hair.
