Androgenetic alopecia (AGA) is the most common type of hair loss and features progressive miniaturization of hair follicles. Generally, the occurrence of AGA has long been thought to be driven by genetic and androgen predisposition. However, increasingly, data proposed ageing and AGA are intimately linked. Elevated senescent cell burden and androgen and oxidative stress-induced senescence mechanisms in ageing may be initial targets to improve AGA. This review summarizes the biological links between ageing and AGA, with special focus on cellular senescence. In addition, we discuss the potential therapeutic strategies for improving cellular senescence in AGA, such as inhibiting dermal papilla cells and hair follicle stem cells senescence driven by androgen and reactive oxygen species, removing senescent cell, and reducing senescence-associated secretory phenotype (SASP).
