Alopecia Areata Causes

What causes Alopecia Areata?

        The exact factors responsible for the Alopecia areata is unknown. Considering that Alopecia areata is an autoimmune disorder (the body considers its own cells as foreign and tryes to eliminate them) which predominantly affects genetically predisposed subjects. There are isolated observations of hair loss after episodes of severe stress, but the most recent studies do not show psychological factor behind the alopecia areata, the Alopecia areata is not a illness "nervous".

        Scientists do not know what triggers hair loss. They assume that the mechanism involves destruction of hair as an autoimmune system reaction. Fortunately, stem cells of hair follicles are not affected by the disease, so the hair can regrow, even after several years of dormancy. Heredity and environmental factors (including viral infections, trauma, chemical or physical stress, etc..) could play a triggering role.

        It is important to protect the skin, eyes and nose of the external factors :

• While protecting the skin from the sun, a good sunscreen may do the trick. For the head, you can opt for wearing a wig, a hat or a headband, which has the advantage of keeping the head cool.
• Wear safety goggles (or sunglasses) to protect the eyes from the sun and dust for those who have lost their eyebrows and eyelashes.
• In case of loss of nose hair, it may be useful to apply an antibiotic lotion into the nostrils to protect against micro-organisms that invade the nose and cause colds, flu, sinusitis, etc.. Ask the advice of a doctor.
