Shannen Doherty's hair is growing back following chemotherapy for breast cancer, and the actress has been showing it off on Instagram. "I think my husband and I are morphing into each other..... #twins #curlyhairdontcare," she said in one recent post highlighting the similarity of her locks and those of her husband, Kurt Iswarienko. Doherty announced two months ago that her cancer is in remission, People reports. "As every single one of my fellow cancer family knows, the next five years is crucial," she wrote at the time. "Reoccurrences happen all the time. ... So with a heart that is certainly lighter, I wait." (More Shannen Doherty stories.)
