Why do criminals have a crewcut or bald head after entering prison?

Besides reasons in answer 1

As in military, minimal hair takes away a style feature thus removing individuality and making one part of the system.

Especially among black, the patterns cut in the hair denote gang affiliations.

Hair care cost money even in the joint. I have worked for one jail where hairclippers were lent out to inmates. Inmates can purchase shampoo,conditioner, hair gel etc from the commissary. If you shave your head every week you spend less money on hair care products. Besides, if you are a guy surrounded by guys, who are you trying to look good for?

My dad shaves his head all the way down to the exterior as quickly as a month, and he makes use of cleansing soap, he suggested it incredibly is much less complicated than shampoo via fact all he has to do is wash his physique, no shampoo or something.

Prisoners often get head-lice. Also, combs and hairbrushes can be fashioned into weapons.

its the same reason that they shave headds in the army the haircut is easy to clean

They get screened for head lice.

Hair would also be something great to grab onto in a fight.

Part of the delousing process these scumbags go through.
