A special type of alopecia (extreme hair loss) is called trichotillomania and is caused by a neurotic nature. People who suffer from this disease pull the hair from their head until they become completely bald. Sometimes the hair loss may start only in certain areas, so people may assume at first glance that the person has some inflammatory skin problem. But if you look more closely, you will notice that new, short healthy hairs are growing on those parts, which means that the disease is not of any physical nature.
This disease does not cause traction to decrease, but it kills the person suffering from it, if by force and with intention. If you are sure that you or someone you know has special symptoms, it is better to consult a psychotherapist, decide on a trichoist.
