Introduction
Androgentic alopecia (AGA) is a chronic immune-mediated inflammatory skin disease characterised by uncontrolled proliferation of keratinocytes, activated dendritic cells, release of proinflammatory cytokines and the recruitment of T cells to the skin. Androgenetic alopecia affects both sexes [1,2]. The condition is characterised by the progressive loss of terminal hairs on the scalp in a characteristic distribution. In men, the anterior scalp, mid scalp, temporal scalp and vertex of the scalp are typical sites of involvement. ‘Male balding’ and ‘male pattern hair loss’ are additional terms used to refer to this condition. In women, the condition is characterised by a general decrease in the hair’s volume, a noticeable widening of the mid-line part and/or a see-through appearance on the top of the scalp. The term ‘female pattern hair loss’ (FPHL) is used to refer to this condition.Read more.....
