Inflammation is commonly seen in androgenetic alopecia and is likely part of the condition itself. Studies by Whiting showed that perifollicular inflammation was present in 40 % of AGA biopsies. The inflammation present in AGA is different than the inflammation seen in the destructive scarring alopecias like lichen planopilaris. In 2000, Mahe used the term “microinflammation” to describe this types of inflammatory process.
