Somewhere in the Talmud is written an opinion about Se’ar Beisha Erva. Meaning that hair on a woman is nudity, could you please advise exactly what Gemara is this drawn from and also what is the stance of other opinion in this particular Gemara page. Since we draw Halacha from this particular opinion, are there other opnions about this Halacha, being more of a tradition than a Halacha?

Shalom U'vracha The Gemara (Berachot 24a) clearly states that a married woman must cover her hair. This Halachah is in the category of Dat Moshe, as opposed to Dat Yehudit, i.e. it is not subject to cultural or social conditions, and does not change under any such circumstances (See Ketubot 72a). The source of the Gemara is the verses in the Torah that deal with the Sotah and say that the Cohen must uncover her hair. From here the Gemara concludes that the rest of the time a woman's hair must be covered. Therefore this is a Torah prohibition and there cannot be another contrary opinion. Kol Tuv,
