Mediterranean hair loss generally refers to seborrheic alopecia, and the disease has a certain genetic predisposition. Seborrheic alopecia is also known as androgenetic alopecia, and its causes mainly include genetic factors and androgen secretion abnormality, but also related to excessive mental stress, excessive tension, poor dietary habits and living habits. In male seborrheic alopecia patients, the proportion of family genetic history can reach about 50%~60%, indicating that paternal inheritance is significantly higher than maternal inheritance. Since seborrheic alopecia has an obvious genetic predisposition, people whose parents have seborrheic alopecia will have a higher chance of their children developing seborrheic alopecia. The causes of seborrheic alopecia are many, and the specific situation needs to be analyzed by a doctor’s consultation and combined with family history and other clinical manifestations.
