Does Stress Cause Hair Loss?

Stress can significantly impact your hair health. High levels of stress may trigger conditions like Telogen Effluvium, where hair enters a resting phase and sheds more than usual.

Debunking the Myth: Does Everyday Stress Cause Hair Loss?

Paradi Mirmirani, MD, a dermatologist with the Permanente Medical Group in Vallejo, Calif., says it all depends on what type of stress you’re talking about.

“Stress because you’re late to work or you’ve got a heavy workload is not going to cause you to lose hair,” she says. Short-term, everyday stress is not going to affect your body in such a way that your hair falls out. It takes something larger to do that. “Something that causes you to lose sleep,” Mirmirani says, “or changes your appetite and raises the level of stress hormones.”

“There has been, for my entire life, this mythical connection between stress and hair. It’s ridiculous.” There is no evidence to support the idea that just because you had a few stressful days last week your hair will fall out this week. “It doesn’t even work that way,” she says.

Is Stress Really Causing “Your” Hair Loss?

Many people assume that everyday stress—like running late, work deadlines, or general anxiety—is the reason their hair is thinning. But in reality, normal, day-to-day stress is rarely the cause of significant hair loss.

Hair loss triggered by stress typically comes from a traumatic or highly disruptive event—something that throws your body out of balance. This type of stress, known as physiological or emotional shock, can shift your body’s priorities, disrupting normal functions like hair growth.

Some common examples of triggering events include:

 

  • A sudden illness or surgery
  • The loss of a loved one
  • A divorce or major relationship breakdown
  • Physical or mental abuse
  • A serious accident
  • Extreme or prolonged sleep disruption
  • Rapid weight loss or nutritional imbalance

These events can cause a condition called telogen effluvium, where a large number of hair follicles prematurely enter the resting phase of the growth cycle, leading to noticeable shedding about 2–3 months after the triggering event.

What makes this type of hair loss different is that it’s often tied to changes in behavior and body function—such as poor sleep, skipped meals, hormonal fluctuations, or elevated cortisol levels. It’s not just “feeling stressed” it’s your body literally reacting and functioning differently in response to trauma.
