There's several types of Alopecia. Alopecia Areata (sometimes referred to as Alopecia Circumscripta;, this is the crown-shaped balding), Alopecia Capitis Totalis (Progressive loss of scalp hair), Alopecia Hereditaria (male pattern baldness), and Alopecia Liminaris Frontalis (Hair loss occurring at the hair line, usually resulting from friction or trauma but occasionally from seborrheic dermatitis).
