2,902. The Process of Shaving for Impurity

Hilchos Nezirus 6:10

Let’s say that a nazir left a cemetery, waited several days, and then re-entered it. In such a case, the days he spent outside the cemetery don’t count towards his nezirus. If he left the cemetery, had the purification waters sprinkled on him, immersed in a mikvah and observed several days of nezirus before returning to the cemetery, those days count for him. Even if he re-enters the cemetery on the eighth day, the seventh day (i.e., the day on which he was purified) still counts for him. If, while in the cemetery, he was rendered unclean by a type of impurity for which a nazir must shave, then he must bring an impurity offering. In such a case, his previous days of nezirus are canceled and he must shave for impurity.

Hilchos Nezirus 6:11

The shaving of impurity is as follows: if a nazir is rendered unclean in a manner that requires him to shave, he must have the purification water sprinkled on him on the third and seventh days, and his hair is shaved on the seventh day. After being sprinkled on the seventh day, he immerses in a mikvah, just like anyone else being purified from corpse uncleanliness. The sun goes down and he brings his offerings on the eighth day: two pigeons or two young doves, one for a burnt offering and the other for a sin offering, plus a year-old lamb for a guilt offering. All of the days of his nezirus are voided and he starts counting all over again. If he shaved on the eighth day, he can still bring his offerings that same day.
