Teddi Mellencamp is sharing two major milestones: a year of hair regrowth "after losing it all to radiation" — and her 45th birthday, which she hopes is "the best year yet."
The Real Housewives of Beverly Hills alum shared a throwback photo of her shorn head, with visible scars from her 2025 brain cancer surgery, to her Instagram Stories on Thursday, July 2. She captioned the photo, "last year on my bday," before adding a current photo that showed her blonde ear-length hair, writing, "For anyone who is curious. This is what one year of regrowth looks like after losing it all during radiation."

Mellencamp was first diagnosed with stage 2 melanoma — the deadliest form of skin cancer — in 2022. She underwent 17 surgeries for the invasive skin cancer, but in April 2025, Mellencamp shared that it had metastasized to her brain and lungs.
Following the diagnosis, Mellencamp has been undergoing regular immunotherapy treatments for her cancer, and said she will continue it for another year. Though in October 2025, doctors told her she had “no trace of cancer,” she said she's "not considered in remission."
Now 45, Mellencamp celebrated the milestone with another throwback photo of herself as a child posted to Instagram.
"Happy Birthday to me! I made it until 45 but not without the help of my friends, family, surgeons, doctors, nurses and all the support from you here," she wrote.
"I apologize in advance to anyone who texts, calls or messages that I don't respond to. I am so grateful to all of you and dare I say, praying this is best year yet. (Yes, this was me not Slate)," she wrote, a reference to her oldest child, daughter Slate, 12, whom she shares with ex Edwin Arroyave, alongside son Cruz, 11, and daughter Dove, 6.
