Who doesn't need a haircut?

According to the information provided, people in the following situations usually don't need a haircut:

1. Death of a family member: In some cultures, after learning the news of the death of a family member, men will not have a haircut or shave for one month or one hundred days. This is considered as an act of expressing mourning and filial piety, which may be related to remembering the old friend and respecting the dead.

2. Women: In ancient times, women generally didn't shave their heads, because they didn't go to barbershops to shave their heads. Instead, they may ask their neighbors to cut their hair to avoid contact with male hairdressers.

3. Monks and Taoists: Monks and Taoists usually don't go to barbershops to shave their hair, but have their hair trimmed by fellow practitioners in their temples or Taoist temples. Barbers don't take the initiative to go to temples or Taoist temples to find business.

4. Beggars: Beggars generally don't shave their heads, because they generally keep a slovenly image. There are some rules among beggars. Only when they decide not to be beggars will the barber shave their heads. Beggars have a principle of "three stays", that is, going home, going to the army and doing things. Only when these conditions are met can beggars be shaved by hairdressers. Solemnly declare: the answer is for reference only, please don't be blindly superstitious.
