At what point after shloshim for a parent is one permitted to shave and get a haircut?
Answer:
When someone comments that his hair is very overgrown and he needs a haircut, this is referred to as “geara” and permits him to take a haircut. In absence of someone saying anything the custom is to be lenient after 3 months to take a haircut. Although the above are the times which one may take a haircut, some re stringent to refrain from haircuts the entire year, unless he has a business meeting or some other occurrence of need which requires him to look presentable.
