Emotional stress is less likely to cause hair loss than physical stress, but it can happen, for instance, in the case of divorce, after the death of a loved one, or while caring for an aging parent. More often, though, emotional stress won't actually precipitate the hair loss.
Here are some other causes of hair loss: Telogen effluvium (say: TEL-uh-jen eh-FLOO-vee-um). This means that more hairs than usual are in the resting phase and fall out more easily. As a result, you lose more hair than usual. You might notice more hair on your brush or a big clump of hair in the drain after you shower. A fever, stress, or surgery can cause this change in your hair. The good news is that you're not going bald and your hair will be back to normal within 6 months.
