I was, however, since I had to board a flight back home, the special shampoo had to be left behind. I was instructed to rinse my hair daily using baby shampoo with no scrubbing. As far as a spray, there was no mention of that in their post op instructions but I believe on the 3rd day, I can apply a zinc based ointment which is also used to treat donor scar site. Not relevant to your question but I might add that I tend to swell pretty horrifically in the forehead after these surgeries. Nothing helps, ice, elevation all to no avail so I'm currently dealing with that which is a little inconvenient since I can't go anywhere until it subsides but hey, a slight sacrifice for new hair so no complaints on this end, just mild venting to get me through .
