7-9 days after FUE hair transplant, I was gently scrubbing transplanted area, I found some hair fall with crust. (Photos)

It is normal to have hair shedding days or weeks after surgery.  If you are concerned it is best to follow up with your doctor.

eklawia,That can be entirely normal. The hair shaft and epidermis or "scab" usually starts the temporary shed at that time. Look for there to be new growth starting anywhere from 2-4 months after the surgery and continuing until most grow in at about 12 months post procedure.Sincerely,Bernardino Arocha, MD

That's perfectly normal. Most transplanted hairs fall out between a week to a month after surgery, while scabs can take up to two weeks to fall. So, during this overlap period they often come out together, nothing to be concerned about unless you are picking off the scabs. However, you should wait until 2 weeks at the bare minimum to resume smoking regularly, ideally a month instead!
