Last year, Shannen Doherty revealed that she's battling breast cancer, and on Tuesday night, the actress shared a deeply personal part of that process.

Doherty — surrounded by loved ones and equipped with scissors, an electric razor and chocolates — shaved off her long, dark hair and documented the event in a series of moving black-and-white photos posted to Instagram.

In the first photo ("Step 1," she captioned it), Doherty looked emotional as her mother, Rosa, held her in her arms.

In the third photo, the 45-year-old was pictured with a short-cropped 'do and getting kisses from her mom and model pal Anne Marie Kotright.

Doherty played with her new style a bit before sharing photos of her final buzzcut.

The pics drew lots of positive comments from Doherty fans.

"You shine like a beacon bad ass woman," one wrote.

"I'm fighting the same battle! We are warriors," another said.

When Doherty first revealed her diagnosis last August, she told People magazine, "I am currently undergoing treatment. I am continuing to eat right, exercise and stay very positive about my life."
