A high hairline can be caused by congenital factors or by diseases such as androgenetic alopecia and creeping baldness. 1. Congenital factors: If there is a lack of hair follicles at the hairline at birth, it will lead to the absence of hair at the hairline, thus resulting in a high hairline. 2. Androgenetic alopecia: the cause may be related to heredity, hormone level changes and other factors. The patient’s hair at the top of the frontal area will gradually become thinner, thinner and less, which may lead to a high hairline. 3. Creeping baldness: the cause may be related to autoimmune, mental stress, heredity and other factors. Patients will have strips of hair loss on the occipital and temporal edges, which may lead to a higher hairline. There are more reasons for high hairline, and after excluding physiological factors, you should go to a regular hospital to find out the cause of the disease.
