Having trouble with cloth physics

hello, so i am working on a character and the hair i made glitched out like mad (the hair uses cloth physics). so, if you open the file, first of all i would recommend not to play it and just go frame by frame, as it may crash if you just play it. and if you go to the hair in edit mode, you’ll see the vertices i have selected for the pinning for the cloth physics. thanks!
note - i forgot to mention this but the hair is on a blocky head if you unhide everything (alt + H), you’ll see it.
here is blend file:
Blocky Elsa.blend (2.8 MB)

ok, i don’t know why, but the hair is working all of a sudden, i did not do anything, so i don’t know.
