How can one deal with the problem of dissatisfaction with a fiancée who is suffering from hair loss after performing Istikhara prayer, taking into account family pressures and the impact of this on one's studies and psychological state?

Firstly: Istikhara (prayer for guidance) is commendable, and its effect becomes apparent in the facilitation and ease of the matter without the need for a vision.

Secondly: A son is not obligated to obey his parents in marrying a specific woman. However, obeying them in this matter is rewarded if the woman is pleasing in terms of religion and character. If he fears incompatibility or dislikes the relationship, he should be frank with them and ask for their forgiveness regarding the annulment of the engagement. It is advisable to think and deliberate before annulment, for if she is pleasing in religion and character and her only flaw is her hair, this can be remedied, and she might even be beautiful with it. He should deliberate on completing the marriage until his soul is at ease and he should supplicate to Allah frequently.
