Love highlights, but aren't so fond of the upkeep? Then look no further than the ombré effect that's popping up. The latest star to join in on the trend is Jessica Biel, who showed off a darker base color, complete with golden blond strands peeking out from the ends, at a photo call for The A-Team in Madrid earlier today. Ashlee Simpson and Rachel Bilson have also been wearing the graduating style as of late, with Ashlee explaining to us the reasoning behind her newer dip-dyed look. It's no wonder stars are flocking to salons to get the style. Not only is it easy to maintain (since roots are encouraged), but depending on the variation of colors you choose, it can also appear either subtle or intense.
