The Lindsay Lohan Hair Terror Alert Scale (PHOTOS)

So our embattled Lindsay Lohan went back to the blonde look, but did you know there’s a reason that Lindsay changes her hair color so often? No, it’s not just because she can’t decide who she is or what she’s doing with her life, it’s because her hair is — much like the Terror Alert System introduced by the Department of Homeland Security — a coded indicator of what kind of behavior we can expect from the troubled starlet.

Is she ‘getting back on track’ and trying to land acting roles, or is she going MIA in a French hotel room with a bunch of sketchballs instead of showing up for her court date? The answers can all be found in her hair color.

Don’t believe us? Click through our Lohan Hair Terror Alert Scale to see what you can expect when Lindsay’s hair is blonde, black, red and everything in between.
