Halachot of Hair
From Halachipedia
Hair is one of the aspects of the human body that can be used to adorn and beautify oneself. There are many halachot that relate to taking a haircut or combing one's hair at special times during the year or day. Additionally, the way in which hair is cut or the areas which are left uncut highlight the spiritual nature of a person's hair, whether it be on one's head or one's beard.
