Well, I'm not sure if it's entirely 'new hair' - although if there are any extensions in there, it might be. But she's certainly got a new hairstyle.
And if you're wondering why Lindsay's looking like she's just stepped out of a salon (in the words of the classic advert) - that's because she just has.
Ms Lohan posed for the cameras as she left her hairdressers - well, who doesn't? - sporting big new wavy, blonde locks (and a very shiny orange face, but we won't dwell on that). And her big new wavy, blonde locks are the work of hair maestro Ken Pavés - a Beverly Hills-based stylist whose celebrity clients include Jessica Biel, Eva Longoria, Jennifer Lopez and Jessica Simpson.
Although, as we now know, if you want to get Jessica Simpson's hair, you don't have to to go to a Hollywood stylist - you can just buy a clip-on version from Macy's. You should try that next time, Linds - it'll save you a fortune!
