This concern is way over rated! I had planned to shut down my personal life for a month. I stockpiled plenty of food. Told everyone of a snow skiing trip across country and of a terrible upcoming work schedule.
By the next day I was driving around town with a ballcap. No one noticed. Three days later, I began dating again - again with ballcap - no one suspected anything. Predinose and almost no swelling. I tried an icepack one time, but it gave me a headache. I just slept upright.
On the sixth day the ballcap came off. On the sixth, seventh and eigth day after surgery, I was so confident I went on three different dates, out to restaurants, no one noticed or suspected a thing. And believe me they are the type that would notice!
I also had no scabbing. I had a "second skin" bandage for three days, which kept the skin constently lubricated with antibiotic ointment. Between days three and six, I just waited for the pinkness to fade. A little hair covers any remaining pinkness very nicely. It is so light anyway, only I would notice. I am caucasion, fair complection.
I hope this helps. I too had judiciously studied the many pictures of guys looking messed up for weeks. Eyes swollen shut, scabby heads for weeks. This concern almost overrode my decision to get the transplant. What a shame that would have been.
