Positive Mitzvah 111: Shaving the hair of a person that has "Tzara'at"
Leviticus 14:9 "And it shall be on the seventh day, he shall shave all his hair"

A person who has become impure with Tzara'at is commanded to shave his hair in the process of purification.

Afterlife is a very rational, natural consequence of the order of things. After all, nothing is ever lost -- even the body only transforms into earth. But nothing is lost. The person you are is also never lost. It only returns to its source. If your soul became attached to the material world during its stay here, then it must painfully rip itself away to make the journey back. But if it was only a traveller, connected to its source all along, then its ride home is heavenly.
