There is no clinical diagnosis of “hereditary alopecia”, but most patients with seborrheic alopecia have a family history of the disease, so seborrheic alopecia is related to heredity. Alopecia areata includes scarring alopecia and non-scarring alopecia, the latter commonly includes seborrheic alopecia and baldness, etc. Most of the patients with these two diseases have a clear family history, so these diseases are related to heredity, but do not belong to the hereditary diseases. The formation of seborrheic alopecia is related to heredity, living habits and emotional factors, etc. It may be based on heredity, the scalp oil secretion is too exuberant, and at the same time, androgens inhibit the growth of hair follicles. Therefore, it can be assumed that “hereditary alopecia” refers to hair loss associated with genetic factors, which is a larger category of diseases, and seborrheic alopecia is one of the diseases associated with hereditary factors in hair loss. For patients with hair loss, it is recommended to go to a regular hospital for a clear diagnosis and treatment under the guidance of a professional doctor.
