Androgenetic alopecia nomenclature

There are many different names for what is commonly called male pattern alopecia. Below is a list of the more common terms that you may come across.

The term androgenetic alopecia is popular among scientists and clinicians as it indicates the hormonal nature of the hair loss and it is not gender specific. "Pattern baldness" is becoming an increasingly poular term and stems from dropping the "male" or "female" from male pattern baldness or female pattern baldness. However, male pattern baldness and female pattern baldness distinguish two different clinical patterns of hair loss and so it is useful to retain these gender specific names.

In some countries the term seborrheic alopecia is used. However, the name is not popular with most scientists and clinicians in the hair research field as the name suggests seborrhea is implicated in the hair loss. It is quite common to have hair loss without any associated seborrhea. Seborrhea and alopecia are two seperate conditions that need not occur together. To avoid making such false associations with nomenclature most dermatologists do not use this name.
