What is alopecia? It is not known for sure what causes alopecia and it is estimated it will affect 1.7 per cent of the population, so you really are not alone. This is not a life-threatening condition but it can be emotionally and psychologically damaging. Between 50 and 80 per cent of people with alopecia have hair growth within one year. However, the condition is known to recur and hair can continue to grow and fall out throughout a person's life. With alopecia there is no loss of hair follicles so there is always the possibility of hair re-growth no matter how long hair is lost for. Hair loss can be utterly devastating. It is a form of disfigurement that can lead to changes in how you perceive yourself personally and socially. The impact on your self esteem can be so severe that your sense of self and identity is broken. Many people with alopecia grieve for their loss, experiencing feelings of anger, depression and emotional numbness. The causes of alopecia are not entirely clear. It is commonly thought that the condition can be psychological, bought on by shock or a stressful/traumatic incident. It may be genetic or the result of a physical trauma. But the favoured theory is that people with alopecia have a dysfunctional immune system. Immune cells treat the hair follicles as alien and attack them, causing the hair to fall out. Psychoneuroimmunology is the science of the mind, the brain and the nervous system, the immune system and how they all interact .
