Looks like Simba has gone bald and he likes his new appearance.
I decided to get Bonaxor to make this once since rarely a male lion has a balding head.
I would think male lions in the lion king would suffer from balding like humans do and Simba could get it. The male lions who go bald would actually love it since it would make them look handsome and better.
Nala would be loving his balding as it make him look better and handsome as a adult lion.
