2 Samuel 14:25-26

25No man in all Israel was as handsome and highly praised as Absalom. From the sole of his foot to the top of his head, he did not have a single flaw.

26When he shaved his head — he shaved it at the end of every year because his hair got so heavy for him that he had to shave it off — he would weigh the hair from his head and it would be five pounds according to the royal standard.
