Watching your hair thin or fall out can be quite distressing but, contrary to popular belief, it’s not always due to genetics. Stress can cause your hair to fall out too. Whether it’s illness-related, from the demands of regular life, or a change in circumstances, stress can cause reactions in your body that cause physical issues, such as hair loss. You may not notice the issue right away as it takes the body a few months to show signs of hair loss. And once hair loss begins, it’s hard to stop it as the hair must go through an entire cycle in order to grow back again.
