A member asked:

Could a dry scalp be an inherited disease?

2 doctors weighed in across 2 answers

Genetics: Genetics are quintessential ingredient of our being, as the interaction of our genetic makeup with the environment that we live in determines many, if not all, of the processes and diseases. For example, psoriasis, an inflammatory geno-dermatosis, may cause dry and scaly scalp. Nevertheless, exclusion of other potential causes by a physician is warranted prior to this conclusion.

Yes: Psoriasis often runs in the family, and it's a fairly common cause of a scaly scalp.
