For a few months now my scalp has been flaking badly (parts of my scalp are white and I can feel the scaly build up) and the top of my left ear is irritated and the skin is flaking. At first I thought I was having an reaction to my shampoo. I switched brands and the issue persisted. I even tried dandruff shampoo to no avail. My mother said it looks like cradle cap like I had when I was a baby. Well, I am 40 y.o. now. I read about cradle cap and that is caused by the seborrhea and sebeceous gland. I do have light bruises on both sides of my neck right below the ears.

Question is: Do adults get cradle cap? If so, what can I do to get rid of it?
