For a woman, she should wipe from the roots of her hair on the forehead until the nape of your head. One time is sufficient but sunnah is to do it back and forth.

sheikh, when wiping the head during wudu, you must wipe back and forth. How can a woman do that if she has her hair tied back or long? Our hair isn’t short as a man’s. Is it enough to wipe only backwards? Guide me.
