What do Brandy, Paris Hilton and Jessica Simpson have in common besides singing careers? They're all endorsing lines of hair extensions. Brandy is the latest to join the faux-hair club, pushing a collection of extensions and weaves made with collagen. They're available in 16 shades designed for women of color, and at $29, they're less expensive than Paris' human-hair extensions and Jess' fake-hair clip-ins.

Initially I thought extensions were expensive and time-consuming, but now that there are some cheaper options on the market—and my hair's in an awkward growing-out stage—I've been thinking of trying them out. Then again, you can always try out celebrity hairstyles online, so maybe I'll just start there. I'm curious to know whether you've tried extensions. If so, was the cost worth it, and did it look believably real?
