If you have a scalp, it’s going to itch at some point. But if the top of your head is severely itchy, you might actually have eczema on your scalp. Yup, it happens.
You might not think you can have eczema if you’re having issues only with your scalp, but it’s possible. While it’s likely that having scalp eczema also means that you have it elsewhere, it’s not a requirement.
