As you can see, all the scabs are now gone and area looks fine, if a little red. After taking advice from Dr Rahal, I massaged the graft area gently when washing to speed up scab removal. The scabs easily came away, with a good few hairs attached I might add, as expected. As far as I'm aware I have not lost any grafts since the op.
I experimented with various concealers for the donor area (dermmatch and nanogen) but after several tries gave up. From afar it was an improvement, but near not so. I'd been in 2 minds whether to use them anyway. Back at work today, and all in a positive experience. Told a few colleagues, while others just thought I'd had a buzz cut. There really is no reason to explain the appearance of either the grafted area or the donor site. I've firmly concluded that I won't waste my time trying to cover up. And answer truthfully if asked questions. I don't need to do anymore than that.
