For the past couple of days I have had these bumps on the back of my neck and on the back of my head. The liquid comes out like a normal liquid but then hardens to an orange looking scab thing. It itches sometimes and when I do itch it it comes off crystally. There's no blood or pus when I itch it, but it does feel like a broken scab if you were to pick a scab off and touch the inner layer of skin. Then on one of the bumps is raised and feels like a bruise. My family says it is because I don't wash my hair well enough or don't lather it well enough, but im not so sure. I don't know if this could be some sort of skin condition and ive looked at several different areas and I haven't seen someone with my problem yet. Thank you in advance.
