I have this also. It drives me nuts. When I was at the skin doctor, he told me that it was keratosis of the scalp.
Your right becklyn, for saying not to take too hot of shower's. I break right out. I also break out with red blouches all of my face and very dry after an hour or so. The hard crusty stuff does not go to my face, just red blouches all over it.
It is very hard to get use too having this. If you keep your hair washed and don't let it get greesy at all,,,,,,it does clear up a bit.
The eyebrow thing,,,,,yes I get that too,,,,,my whole face get's dry and cracky.........But mainly around my scalp area.......Keep your face washed and keep the oil away.
Have a great day
