I had 3000 FUT grafts over 2 days, the day after the 2nd I felt perfect. Walked around a trade show all day while wearing a ball cap. I just loosened the strap in back, made sure to gently place it, it didn't touch the grafts from crown to hairline, and the strip was snugly stitched up on the sides and back. I would be careful that it's not pinching anywhere or tight, ask your surgeon too. Do you go back to your surgeon the next day for a post op washing of area and check? You'll be wanting to sleep upright for several nights, regular icing and saline misting of areas too. Wouldn't want to be in airports too much of the following day letting the grafts dry out or swelling to take hold. Best of luck to you, you'll do fine!
