Addressing Androgenetic Alopecia-A Complex Disorder-with a Multilateral Treatment Strategy

Androgenetic alopecia (AGA) is a disorder that involves gradual loss of hair in genetically predisposed individuals and is more prominent in men than women. Ethnically, white male are affected the most [1]; the estimated prevalence of AGA in Caucasian populations by the age of 80 is over 90% [2]. Physiological changes which occur during AGA include hair follicle miniaturization and variations in normal hair cycle; specifically, anagen phase length shortens and that of telogen phase stays same or prolongs [3]. In addition, the overall follicular apparatus is also gradually miniaturized which leads to global reduction of hair density due to conversion of terminal hair into vellus hair [4,5].
