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.
When stress is the cause, hair will grow back over several months. A serious deficiency in protein, iron, zinc, or other nutrients can make hair fall out. Hair loss in women can also be a symptom of a disorder such as lupus or diabetes. Some medications can cause hair loss. Common culprits include lithium, beta-blockers, warfarin, and heparin. This is an autoimmune disease that makes hair fall out in small, round patches. In some cases, it can cause total baldness. A corticosteroid applied to the scalp or injected can help.
