Miller posted an update about her health on Instagram over the weekend and shared that she is undergoing another round of chemotherapy and may lose her hair.
"HAIR TODAY, GONE TOMORROW…" she captioned an image of herself with her hair down, also writing "#chemo" in the post.
Since then, Miller has been keeping her fans updated on her treatment and recovery process. Last month, she shared a photo of her healing scar, and last week she posted an image of herself in a wheelchair on Instagram. She also revealed she underwent emergency surgery after a two-hour MRI earlier this month.
According to an Instagram posted earlier this month, Miller is currently in her third round of chemotherapy. "Another battle that I must win!" she wrote at the time.
As SELF wrote previously, hair loss is one of the most common potential side effects of chemotherapy.
Chemotherapy is great at killing fast-growing tumor cells, but it can't distinguish between those cells and healthy cells that also happen to grow quickly. That means it might also target the cells in your digestive tract, mouth, and hair follicles, meaning that, yes, chemotherapy may cause you to lose your hair.
According to the American Cancer Society, hair loss occurs when chemotherapy drugs damage hair follicles. It most often begins within the first two weeks of treatment, and intensifies one to two months into chemo. However, in most cases, the hair begins to grow back before treatment ends.
