I am 5 weeks post op from my 1800 graft procedure. Most of the grafts were placed to lower the hairline, and it is still quite red. I am lucky enough to be able to wear a hat to work, but I was just trying some foundation(make-up for skin blemishes or redness) and it worked very well to conceal the redness. My question was will foundation or any other make-up effect growth of the grafts? Plus I will only use it a few more weeks until the redness goes away.
