Just as ombre hair was on its way out the door, the trend has boomeranged back, only this time it's  in the form of a manicure.

Take Lauren Conrad for example, who not only rocked blue-streaked strands at the HTC Status Social launch event in Hollywood on Tuesday, but also sported an ombre manicure.

From thumb to pinky, each of her fingernails was painted one shade of blue darker than the other -- from periwinkle to dark navy and black.

The Hills alum, 25, has a penchant for trying out new hair and makeup trends -- so much that in addition to penning her own style guide, she co-authors a blog,, with her hairstylist, Kristin Ess, and makeup artist, Amy Nadine. Here, fans can find step-by-step instructions on how to get everything from LC’s giant ballerina bun to her edgy winged liner.

Currently the trendsetting star is getting ready for the launch of her new clothing line, Paper Crown, which is due to hit stores like Nordstrom and Fred Segal in early August. This will be Conrad's second stint at designing womenswear -- she also has LC Lauren Conrad with Kohl's.
