Can you imagine having a bad hair day, every day, for years? It happens to most cancer survivors, because chemotherapy makes their hair fall out. Once treatment is over, it grows back, but it's different. It's usually dark, wiry, and impossible to style hair that's been dubbed "chemo-curls." In fact, many sufferers compare chemo-curls to a really bad perm that won't go away. So, what causes chemo-curls? Experts say radiation from chemotherapy wipes out all cells, including healthy hair follicles. It can take a year and a half for the toxins to flush out of your hair follicles and for your regular hair to grow back in. Even though you might think after beating cancer, it would be easy to adapt to something harmless, like new hair, it's one of the most traumatic things a cancer patient can experience. Dr. Jyoti Patel is an oncology professor at Northwestern University. She says that every time a cancer survivor looks in the mirror and sees chemo curls, it's a jarring reminder of their painful cancer journey, and it triggers intense memories. Also, many women say chemo-curls are a visual reminder that they're "different," and are still affected by cancer, even if they're in remission. So, a growing number of women are craving chemo-curl support. They're not turning to hair salons to tame their new hair. Instead, they're going online, and blogging about life with chemo-curls. They're also uploading videos on YouTube where they do everything from share tips on the best shampoo for their new hair, to make fun of the wacky ways they style their new curls. Experts say the blogs and videos make women feel like they're not alone, but part of a close-knit community with others who know exactly what they're going through.
