Which sprite sheets should I be editing?

i’m planning on making a custom male trainer sprite, but i’m a little confused as to what i should do about the hair (which was the main point of this endeavor) since there’s no trchar179_hair equivalent. if anyone knows which files i should be editing in addition to trainer178 - trback178 - trchar178 - trchar178_bike and trchar178_run (or if those are even the correct ones) that’d be super helpful!
tbc, i only want to edit one of the three options at the start of the game, but if it’d be easier to change all three i don’t mind.
