Dry scalp also dry skin in eyebrows also in beard in mu stash. can get irritated and red sometime?

Seborrheic dermatitis: That red, itchy rash on your scalp that has flaky scales could be seborrheic dermatitis, or seborrhea. It's a common skin disease that looks similar to psoriasis, eczema, or an allergic reaction. And it can appear on your body as well as your scalp

Dry skin: It may sound strange but I recommend you go to a hair salon. The team will either take good care of you - very likely, but you must also see your doctor about the beard, eyebrows etc. I have a beard that I control (at least that is what I think), but you should see an Eye doctor some time soon. Hope all goes well!
