Hello and welcome to celebrity hair analysis. Today we want to talk about Jojo Siwa. Darling little girl, famous for the tight ponytail. She may be suffering from something called traction alopecia. What is that? In Greenland in the 1900s, women pulled their hair back so tight hair loss around the hairline was occurring. From some of Jojo's pictures, she seems to be thinning a little bit at the hairline.

It doesn't look like there would be a lot of other explanations for the hair loss. Now we're not doctors. We've never met her. This is not a medical diagnosis. We want to use this as a time to share information with you. Give examples of some of the things that can cause hair loss.
