Hi Janie!
Oh my yes! I have small brown colored "rock" type things, orange petaloid looking things as well. I apply medicines on my scalp with a Q-Tip, and the swab always looks dirty after rubbing it on my scalp. My scalp has a dirty yellow tinge too. I am always amazed at the crud that falls off my scalp. I wish it was just flakes. HARDLY! I have scales of all sizes and shapes. Mostly thin and white, but some are very big. I have a wet substance that comes from my scalp that is gross, it smears all over my clothes, on my furniture, wherever, whenever it's present. Some flairs have big chunks of stuff that fall off my scalp, And sometimes the dry flaky skin just falls willy nilly from my head. I have never been so perplexed over anything in my life! I hope I helped answer you, even if it's yucky!
