It's been a helluva hairy summer for Dianna Agron.

The Glee starlet made a huge style change when she chopped off her long blond locks for a shaggy, cropped 'do back in May, and that apparently opened the flood gates for more hair transformations...

Di jumped on the rainbow hair band wagon last Thursday—joining Katy Perry, Sienna Miller and Kate Bosworth—when she debuted a hot-pink hue while grabbing an icy drink in La-La Land.

By the weekend, however, the fuchsia had faded to a pale pink when the 25-year-old actress was spotted at the Greek Theater catching the Adele show.

But just yesterday outside an L.A. grocery store, her hair was bright pink again!

Quinn Fabray's alter ego recently explained on Twitter: " Hey all! The pink is for work. Tried to keep it a surprise...so, that is all I will say! Thanks for all the nice comments on it! #barbiepink."

The adorable babe's obvs been busy filming the third season of the hit show. Is the cast doing some kind of No Doubt ep? After all, Gwen Stefani is one of the original hot-pink mop heads.

Will you be glad or bummed when Dianna goes back to a normal human hair color after filming? Weigh in below!
