I am a sixteen year old female who recently discovered a patch of hair on the left side of my crown that is very oily/sticky. It feels as if there is some kind of product in my hair. It even stands up on its own as if I put gel it in. (I have very short hair). I have washed it several times even with harsh soaps, and yet it has not gone away. I do use a hair product called Spiker, which is hair glue, but I wash it out every night. This has been persisting for about a week, now. What is this and what can I do?
