Lauren Conrad isn't the only Hills alum to make a major hair change. Whitney Port showed off a new reddish color at SVEDKA's Night of a Billion Reality Stars party in L.A. on Thursday.

So what prompted the 25-year-old to dye her long blonde locks? "We changed just because we can! That's what hair color is all about," the star's hair pro, Kristin Ess told UsMagazine.com of the color she jokingly calls "apricot gingersnap."

To get the desired effect, Ess first applied an apricot base, followed by a matching gloss to add shine and help lock in the new color. Then, she topped it off with a few fine blonde highlights around Port’s face and at the ends so it looks natural.

"Whitney loves it. She's already feeling comfortable [as a redhead] and that's most important," says Ess.
