R. Kahana questioned Rabh: "What about a hair-net? Answered Rabh: "You mean to say a woven one? Everything woven has not been restricted." This was also taught in the name of R. Huna b. R. Joshua. According to others the same said: "I have seen that my sisters were not particular to take it off while bathing." And the difference between the two versions is when it was dirty; according to the first version, it does not matter, as everything woven was not restricted; and the second version, where particularity is the case, if they were dirty, they would certainly be particular to take them off.
An objection was raised from Mishna [Miqvaoth, IX. 8]: "When a person bathes, the following objects cause 'intervention' (Chatzitzah): Woollen and linen bands and headstraps (used by maidens)." R. Jehudah says woollen and hair bands do not cause "intervention," because water soaks through them. (Now we see that although woollen and linen bands are woven, yet they are an intervention.) Said R. Huna: "All this concerns only maidens." (And they are an intervention only because they are particular about it.)
R. Joseph in the name of R. Jehudah said that Samuel said that the Halakha prevails according to R. Jehudah in the case of hair bands only. Said Abayi: From the expression "the Halakha prevails" we must infer that there is a controversy between R. Jehudah and the Tana of the above Boraitha. (The Tana said nothing about hair bands.) Shall we assume that because R. Jehudah declares hair bands not to be objects of "intervention," he must have heard the previous Tana mention them? Even if such be the case, it is not probable that R. Jehudah heard that the Tana agrees with him on that point, and hence he says: "If he agrees with me on this point, why not in the other instances also?" Said R. Na'hman in the name of Samuel: Read, The sages agree with R. Jehudah with respect to hair bands.
This is supported by a Boraitha. Woollen bands cause intervention, but hair bands do not. R. Jehudah, however, said: "Neither of them causes intervention."
Said R. Na'hman b. Itz'hak: It seems to be so from the expression of our Mishna: "A woman may go out with hair bands, be they her own or her friends'." Whose opinion does this Mishna represent? Can we say R. Jehudah's? He permits even woollen bands. We must say it is in accordance with the above rabbis; hence they do not differ as regards hair bands.
