my menstrual cycle is always atleast 7 days long. at first it was 7 days, recently it is as long as 9 to 10 days! and i have heard that one should avoid washing hair (or taking bath) during menstruation. i never really follow this thing coz i cant go without washing my hair for more than 3 days (it obviously gets filthy by that time). so i just wanna know, does any one know if it;s okay that i take regular baths during my periods?
