Working night shifts can seriously disrupt your body’s natural clock and your hair isn’t immune. Hair follicles have their own circadian rhythm, which regulates when they divide, grow, or rest. When you’re chronically misaligned (like with rotating or overnight shifts), these clocks get out of sync. That may push more hairs into the resting (telogen) phase and slow their growth, leading to diffuse thinning rather than patchy baldness. Over time, fluctuating hormones and metabolic stress compound the problem. For shift workers, this means more hair shedding and less recovery between stress cycles.
