Is it permissible for a married woman to wash her hair daily in part to save effort, especially since her husband asks her to adorn herself for him daily, and is it permissible for her to wipe over the middle or end of her hair during ablution instead of the front part of it?

"It is not sufficient in the obligatory ghusl (ritual bath) to wipe the hair or to run wet fingers through it. Rather, the entire hair must be washed with water until the water reaches the roots of the hair. What you mentioned is not an excuse for abandoning the washing of the hair or for merely running wet fingers through it. As for limiting oneself to wiping only part of the head during ablution (wudu'), it is permissible according to many scholars, though it is more cautious to wipe the entire head. Wiping the forelock (nasiyah) or a part of the middle or back of the head is sufficient."
