Shannen Doherty, the '90s TV star who many of us came to love as Prue Halliwell on "Charmed," just got vulnerable about her cancer battle in the most beautifully brave way. 

Early Wednesday morning (July 20), she revealed she'd shaved her head, presumably in response to her ongoing treatments, by sharing a series of intimate photos on Instagram. Doherty first spoke publicly about her battle with breast cancer in August 2015. 

Doherty's mother, Rosa, was there to support her during the emotional makeover.

The vulnerability in this mother-daughter photo truly makes me misty-eyed. 

As was her close friend, the model Anne Kortright-Shilstat. Here, she captures Doherty taking the first snip.

In a touching message of solidarity, Kortright-Shilstat wrote in an Instagram post that she "couldn't be prouder" of Doherty for her bravery. 

"Your strength and courage is so inspiring and I am so very lucky to have you in my life," she wrote. "Thank you for blindly trusting me today to help you with such a big step. I will forever be there for you no matter what. #fuckcancer." 

Doherty has spoken about striving to maintain a grounded perspective throughout her treatment, saying that "ultimately, they're just breasts, right?"

On the "Dr. Oz Show" in February, Doherty said she and her doctors were still choosing between two different surgeries, but that she was open to getting a mastectomy if necessary.

"Ultimately, they're just breasts right?" she said. "I mean, I love them, they're mine, they're beautiful, but in the grand scheme of things, I would rather be alive and I would rather grow old with my husband (Kurt Iswarienko)." 

She and her husband have been married since 2011. He said the cancer battle has brought them even closer.

"For us, it has brought us closer together," Iswarienko, a photographer, said. "It's one of those times you get to test your mettle as a married couple." The couple recently vacationed in Sydney, Australia, for his birthday. 

Doherty said she worries most about how her family and friends are handling her illness, but she also has concern for her career.

"'I think that people think that I’m 'sick' and therefore I’m unable to perform," she told Dr. Oz. "What will I be like on a set, and will I remember my lines, and will I be able to make it every single day? And the answer is yes, of course!" 

Doherty will star as Charles Bukowski's mother in the James Franco-directed biographical film "Bukowski," which was delayed due to a lawsuit but is set to be released later this year. She's also starring in "Mallrats 2," the sequel to the 1995 Kevin Smith movie. 

"I’ve been lucky I have a director that adores me and hires me for a lot of stuff and another director like Kevin Smith, but you know those are few and far between," she said. "I think that most people are usually like, ‘Oh God, is she okay?’” 

Her vulnerability about a battle so many women so face is as inspiring as it is important.

For an actress who for so long has been widely associated with sex appeal (she was on the cover of Playboy in 1994), choosing to share with the world the loss of her hair is so strong of her. And that makes her more beautiful than ever.
