Does Lauren Conrad have hair extensions?
Yes she does. At the end of Season 3, she had short hair. A few months later when Season 4 started, she had long hair. They didn’t film those seasons completely. So as soon as the finished filming Season 3, they started Season 4. & maybe a month or two or three later, they aired it. So I highly doubt her hair grew that much in a few months. & on youtube.com, you can see footage from a paparazzi of Lauren getting her extensions.
