Teddi Mellencamp is showing off her brain surgery scars and asking for hair tips amid her cancer battle. Taking to Instagram on Thursday, April 30, the Real Housewives of Beverly Hills alum, 44, shared a photo of the back of head, which showed her scars. Mellencamp also uploaded a video of herself via the post, asking her followers for help with how she should style her hair as it continues to grow back following the surgery. "Now what? The hair is too long for the wigs," Mellencamp said via the video, as she ran her fingers through her hair.
