Does anyone have scalp issues?

So this isn’t about hair loss cause I am one of the lucky people who don’t experience that, but I do have issues with dry skin and build up of thick scaly patches on my scalp that have been around for years. I recently went to the dermatologist and they said it could go hand in hand with my PCOS. I was also told that instead of the seborrheic dermatitis that I was originally diagnosed with, it could be just one giant fungal bacteria issue that is worsened by my PCOS. Does anyone else experience this? I just feel like I’m going crazy and I’m curious
