Friday ghusl is not obligatory upon a woman
Q: “Is the Friday bath (ghusl) obligatory upon a woman?”
“If the Friday prayer fundamentally is not obligatory upon her, then how can the subsidiary issue (the bath) be obligatory when the fundamental (the prayer) isn’t?”
 Shaikh Bin Baaz, Shaikh Ibn al-`Uthaimeen and Shaikh Fawzaan likewise said that the Friday bath is specifically for men – those who must attend the Friday prayer – not women.
