Protective effect of autophagy in particulate matter-induced hair loss

Particulate matter (PM) is among the leading environmental causes of diseases worldwide, and increases mortality and morbidity from cardiovascular and respiratory diseases [1]. Interestingly, increasing evidence suggests that PM is related to hair growth. PM of small diameters can penetrate hair follicles (HFs) in vivo and induce cutaneous inflammatory responses [2]. Recently, an epidemiological study demonstrated that PM concentration partially corresponds to the flare pattern of alopecia areata, the most common inflammatory hair loss disorder [3].
