Answer 1

You think people would want to try and shave the head of a squirming 3 year old boy? That would be likely to cause injury so obviously that is not done.

They cut the hair of the head except for the area of the peyos. So the hair at the temples of the head down through the sideburns is left uncut. Keep on learning and read more here:
