Shannen Doherty took a walk down memory lane on Monday when she uploaded a very personal video of the day she shaved her head on Instagram. In the clip, Shannen is shown laughing as her friend Anne Kortright-Shilstat shaves her hair with electric clippers. "This day..... laughing thru the tears. Thank you @annemkortright for jumping in and doing what needed to be done. @themamarosa," she wrote. Shannen has been incredibly open about her cancer journey [2], and earlier this month, she attended the Animal Hope and Wellness Foundation's Gratitude Gala [3] in LA just one week after finishing chemo.
