With friend Anne Kortright-Shilstat and mom Rosa Elizabeth by her side, Doherty then walked fans thought the emotional process, a series of black and white photos. Rosa Elizabeth embraces her daughter in one photo – both ladies looking as if they’re carrying the weight of the diagnosis and head-shaving process heavy on their hearts. Doherty, 45, chopps her own hair off in another photo, and pauses for a smiling photo with her mom and friend in another. She appears to have some lighthearted fun with the process at one point, letting her hair stand up on its end and smirking at the camera. By the end, the Beverly Hills 90210 alum appears strong, smiling in a selfie with Kortright-Shilstat and her short-new haircut.
