2,893. Unintentional Hair Removal

Hilchos Nezirus 5:13

If a nazir shaves his whole head, he’s only liable to one set of lashes for shaving. If he was warned not to shave before each hair but he chose to do so anyway, he’s liable to lashes for each hair.

Hilchos Nezirus 5:14

If a nazir rubs his hair with his hands or scratches with his nails, he need not be concerned because his intention is not to remove hair and it’s not an inevitability that he’ll do so. He may not, however, use a comb on his hair or rub his head with dirt,* because doing so will certainly remove hair. If he does, however, he isn’t liable to lashes.

*An ancient shampoo, I believe.
