Audrina Patridge has lightened up -- again!

After ditching her blonde streaks in August for a rich, dark brunette color, the reality TV star is has returned to the bright side with blonder hair.

The Hills alum debuted her new ombre mane, which is darker at the roots and blonder at the ends, during a Sears appearance in Cerritos, Calif. on September 28.

The last time the 26-year-old natural blonde rocked a full head of sunny strands was in March when she ditched her glossy brown color for her short-lived VH1 reality series, Audrina.

The reason Patridge, a California native, continues to switch back and forth between being a blonde and a brunette?

"I miss being a brunette. I feel like there are so many blondes in L.A.!" she told Us Weekly.
