Eli5. Why do you only get dandruff on your scalp and not anywhere else? What causes flakes to happen

Since your scalp is just skin like everywhere else like your arms etc why do we get dandruff up there, since it’s just skin, why does your scalp that gets all those flakes?


This is a stupid question, please no hate. I have autism and perseverate, wonder about weird things and I don’t always comprehend well. :)

You do get dandruff everywhere on your body (I believe you shed all your skin every two weeks or so). The reason we seem to see more dandruff on our heads is because the skin gets trapped by your hair.
