LEV155 A metzora's purification requires that he shave off all of his hair. The metzora is to regard his purification as a new beginning for him, and his hair, too, must have a new beginning. As his hair makes a new start, the metzora makes a new start, too, regarding his deeds, because when one's body is hairless, it is easier to cleanse oneself of unwanted dirt. So, too, when a metzora is in the midst of the process of becoming free of impurity, it is fitting that he shave his entire body, for such shaving demonstrates his readiness to do everything possible to cleanse and purify himself. The act will inspire him to change his deeds, too, converting them from bad to good, purifying them to the greatest degree possible.
