Lauren Conrad paid a visit to the Byron and Tracey Salon in Beverly Hills on Friday, and the former reality starlet made every effort not to smile at our photographers. Eh, we're used to it...

The previous day LC wrote a post on her blog all about highlights ... her number one suggestion? Go get it done at a salon. Well, obviously! Lauren also recommends taking it easy with hair products that have alcohol in them and "embracing a much more natural aesthetic when it comes to coloring [your] hair."

Funny, because her hair looks a little busted in this pic ... maybe she was just stopping by to pick up products?
