According to scriptures one should not take head bath(hair wash) on Sunday
One who forsakes on all Sundays, Woman oil bath, meat and drinks, Will never be sick nor sad nor poor. And would reach the land of sun after death.
Assume that a women is following the above and if Sunday is the day she has to take head bath(hair wash) for the reason of completing her menstruation cycle(i.e., on 4th day).
In this situation what a women has to follow?
