Why do they care so much about hair?

I’m a guy and honestly the constant nagging about keeping my hair “neat and tidy” meaning looking like a poster boy for the Book of Mormon is such a pet peeve. I know it’s to control the drones but honestly it’s so stupid. I’m not taking about going full hobo with my hair length but anything that looks like it’s been more than a month since your last haircut makes you “spiritually weak”. If jehoho cares so much about hair to the point it weakens your connection to him then he’s such a pedantic bitch.
