The politically correct term for a bald eagle/supermodel in this case is “traction alopecia.”
It is of course a form of hair loss, but instead of it being a disease that is basically out of your hands, traction alopecia is caused by a “pulling force applied to the hair,” such as braids and/or hair extensions.
The paparazzi have the sequel to that. Recent photos of Naomi in Ibiza depict even more of a bare patch, quite a sizable and sad area, in fact. I would make a joke about karma but it’s not my style.
