Is scalp breakout and itching during chemo normal?

Hair was falling out so just had it buzzed off, but scalp was breaking out at the back and itchy even prior to getting hair buzzed off. What is good for this? I think it’s from scalp being hot and I sweat when I sleep. Getting cool pillow and satin pillow case. Hope that helps. I may need to see Dermatologist. Just wondering if this is normal.
