itching and scratching the scalp

I know this question might be silly, but I’m a little concerned. Some nights I find myself waking up from my sleep while itching my scalp really hard, like nails digging in a little in my scalp. Nothing too intense of course, but just enough to have some flakes peeling off.

I’m kind of freaking out that I’m causing some bad damage to my scalp. I was looking for input from people knowledgeable on the matter, or have had any similar experiences and know good remedies.

Any input would be appreciated.

Scalp scratching causes hair loss and can introduce folliculitis. Never scratch your itch other than rarely and softly
