Is Hair Transplant Permissible for Bald Muslims?
Question

Is it permissible for a bald man to have hair transplanted to his head, because some men suffer with that, especially if they are young?
Praise be to Allah.Shaykh Ibn `Uthaymin (may Allah have mercy on him) was asked about the ruling on taking hair from the back of the head and transplanting it in the affected spot.
He said:
Yes, that is permissible, because it comes under the heading of restoring that which Allah has created, and of correcting a fault. It does not come under the heading of cosmetic procedures or adding to that which Allah has created, or changing the creation of Allah. Rather it is restoring something that is missing and correcting a fault.
It is well-known in the story of the three men, one of whom was bald and said that he wished that Allah would give him back his hair, that the angel touched his head and Allah gave him back his hair, and gave him beautiful hair. (Narrated by Al-Bukhari, 3464 and Muslim, 2964)
