Is thalassemia a problem for a hair transplant?

There is no "dent" after a FUT or strip surgery. It doesn't matter if you have a tight scalp or a loose scalp. If you are having issues, it is best to discuss with your doctor.

1000-1200 grafts be taken from the donor site without any noticeable thinning in the area.  In general you can have well over 4000 without noticeable thinning.  This all depends on how short you keep your donor hair.

It is best to ask your surgeon about post operative care as each doctor has their unique regimen.  Most doctors recommend that you wait until everything has healed.

Strip scar will always show if you keep your hair very short. If you are concerned you can consider SMP but the scar may still be somewhat visible (if you keep you hair very short).

It is best to ask your surgeon about post operative care as each doctor has their unique regimen.   It is also a good idea to talk to your doctor who is treating your other medical condition.

Illegal drugs are not generally recommended after surgery.  If you are concerned it is best to check with your doctor.
