What It Means When Your Hair Falls Out

What's going on: Major psychological stress, whether it's chronic work anxiety, the end of a relationship or the loss of a loved one, can trigger hair loss, says Ranella Hirsch, MD, a board-certified dermatologist in Boston. "It's one way of the body saying, 'Hey, we have to work on this,'" she says. (Hair loss can also happen if you've been through a major physical stressor, like pregnancy or illness.)

How to fix it: Figure out the best way to keep your stress in check, whether that means seeking the help of a therapist, meditating, exercising, etc. Once you're in a better place psychologically, the hair loss should start to resolve itself, Nazarian says.
