My head feels very very tight 4th day after FUE Hair Transplant is this normal? (photos)

Protocols vary for each surgeon, but most will recommend keeping the implanted grafts moist with some kind of spray.  This will prevent the grafts from drying out, thus, gradually allowing the scabs to form so it's not all at once.  The donor area is usually kept moist with ointment for several days post surgery.  Once you are allowed back in the shower, which is usually about one week post op, the scabbing will fall off and your symptoms should subside.

It is best to contact your surgeon for post surgery issues and care since all doctors have slightly different instructions.

Hello. I see you wrote about a month ago and I’m wondering if you are feeling any better? If you are not I hope you've made an appointment to see your doctor.

The crusting is making it feel tight. This is relatively normal however the crusting should be out by when you are. Talk to your surgeon. Soaking in shampoo can help the crusts but doing that at day four might be too early. Your Turkish doctor should be walking you through this. 

Your crusting on the recipient area should have been washed off on day one, Now you will have to leave them on for a good two week before the shampoo can take them off slowly.
