I mean, following canon Alastor story his hair should be big part of his identity. I think he just would avoid cutting what's left of it.

To justify Alastor's terrible hairstyle choice, I will just create the hc that the longer you have been in hell and therefore you became the worst version of yourself, you get ride of your humanoid traits.

AKA, bye bye pretty black hair.

Somehow i like more the hair flat ver.
