Can a dermatologist help with itchy skin?

Hello. I am a man in my 30s.

Whenever the seasons change, my skin gets incredibly dry and itchy, which is really bothering me and stressing me out. It's so bad I can't sleep at night, and when I scratch, my skin turns red and bumpy.

I apply moisturizer thoroughly after showering, but the itchiness doesn't go away easily and it only seems to help temporarily.

Anyone who has experienced similar symptoms to mine and has found any effective treatments or recommended products? What kind of help can I get from a dermatologist? Are there any simple home remedies that can help relieve the itchiness?
