"Learned a valuable lesson in this meaningless process. Bleached my f–king natural healthy a$ hair rebelling out of boredom while dealing with a consecutive amount of time off on the Woody project," she captioned a makeup-free selfie in bed. "Something inside told me I'd regret it…. That hair color comes in a box."

She admitted that she might chop off her hair again because of the damage caused from the at-home dye job.

"Either this shit needs to grow out at super speed or I'm about to go in for a f–kin hair cut realllllll quick!!! #imisstheoldme," she continued.
