Question: My wife complains of her hair falling out a lot and it was said to her to cut it short as this will reduce the falling out (of the hair). Is this permissible?
Response: If the situation is as mentioned, then it is permissible (to cut the hair short) since this will prevent further harm.
And with Allaah lies all success and may Allaah send prayers and salutations upon our Prophet (sal-Allaahu `alayhe wa sallam) and his family and his companions.
