Why do cops shave their heads?

Most people shave their heads because they want a change. Also some people believe that their hair covers up who they are and they want to be known for their personality not looks. Another reason is that if you live in a hot country hair makes you feel really hot and alot of people shave it all off.

Well it can be for stress, desire, they need to, or from being sick, or they just feel like it. So if you see a bald person, you people can ask them why and it will be anyone of those answers.
