It can also make your hair fall out, triggering hair follicles to enter a “dormant” phase that results in hair loss. And now, according to a paper published Wednesday in the journal PLOS Global Public Health, researchers have discovered that stress levels are also reflected in how much of the hormone cortisol is stored in your hair.
