Carolly, I don't think the skull cap has anything to do with this :) The specular color is usually really light, like a grey or a tan. For some reason, its loading too dark. I've noticed the P6 hair looking dull to me too, but I haven't bothered with it since I've still been just playing with the lights. I've played a bit with some of the P5 dynamic hair in P6 and it looked fine so it tends to make me wonder what is going on. As far as the noise showing up, its supposed to be there. I had it in P5 when I was using the RDNA hair mats.
