Circulating and/or cutaneous irisin resistance: A novel link among androgenetic alopecia, comorbid metabolic syndrome and cardiovascular risks.

Background: Androgenetic alopecia (AGA) is a common cause of hair loss in both genders that may be associated with disturbed systemic metabolism. Irisin is a hormone-like myokine that greatly influences systemic metabolism and is linked to cardiovascular diseases.

Aim: To detect irisin role in AGA and its associated metabolic syndrome (MetS) and cardiovascular risk.
