I thought so too...

...balding is caused by a change in testosterone...

There are references to 'hairstyles'...

"Certain hairstyles and treatments. Excessive hairstyling or hairstyles that pull your hair tight, such as pigtails or cornrows, can cause a type of hair loss called traction alopecia. Hot oil hair treatments and permanents can cause inflammation of hair follicles that leads to hair loss. If scarring occurs, hair loss could be permanent."

I have seen edge ups scar...so...yeah, there's that.
