My head is unbearably itchy. ㅠㅠ

I've been experiencing scalp itching for the past two weeks, thinking I might be getting white hair, but the itching has worsened over time and now it itches all over, not just in one area.

It itches so badly that I keep scratching, but I'm worried I might hurt my scalp, so I'm considering whether I should go to the dermatologist.

This is my first time experiencing this, so I'm feeling confused, and especially at night, the itching gets worse. ㅠㅠ
