I am 7 days post op FUE. The last 3 days I've had discomfort in donor area which has some relive with ibuprofen 600mg as needed. Since it was itching a bit and the discomfort seemed to be in areas of crust in donor area, I gently scraped off a few hundred dandruff/blackhead looking crusts from donor area. My question is, was that the hair roots that I scraped off that's suppose to grow back in the donor area? Or was it ok to scrape off those little crusts? Please see pic of crust removed.
