The stress can cause hair lost, but also remember the strong hair dye they've used. Red is not an easy color to keep up with, it was to be re-dyed every few weeks, I know that from personal experience, it can also cause hair to fall. Nonetheless, I hope Exo gets the break they deserve
@SimplyAwkward. Correct, we don't know. It could just be how it's always been too. (Baldness can also be sex linked trait, so the mother could carry it). All idol groups could probably use a break. Honestly, I don't see EXO as one that does at the moment. There are certain members that do though. I see other groups that have been working nonstop, in the public eye, for months without a break.
