Hey, I followed this but remained spraying every 30 mins or so until about day 6 when the scabs were loose. They provided some repair cream which was applied to donor 2x a day. As I was ahead of schedule once the scabs were off I was basically back to normal (day 6/7). Hair wise I just had it brushed back and not covering the grafts. For sleeping I just used a normal pillow with a neck/travel pillow on top, no elevation. I've now implemented Nizoral shampoo as my scalp became really flakey.
Don't be worried, just follow the info your Doc gives and you will be golden.
