תלמוד על נזיר 6:3

⁵⁴This paragraph, the only one in the present series, does not refer to the rules of holidays but to those of a nazir(Nazir6:3 Note 169). One of the obligations of the nazir is to let his hair grow; he is forbidden to tear out a single hair. Therefore it is a question whether he may rub his hair with coarse cloth (in this case Cilician, κιλίκιον). It is permitted only for persons with healthy hair. There are Tannaim who state that one separates with Cilician cloth, and there are Tannaim who state that one does not separate. Rav Ḥisda said, he who said one separates, for healthy {hair}; he who said one does not separate, for weak {hair}.
