Alopecia Areata - Small Patches Of Hair Loss
Alopecia areata is defined as small round patches of hair loss, which may go away on their own or it might last for many years. This disease attacks the hair root and leads to hair loss. Sometimes it affects other parts of the body also. Alopecia areata affects children, males and females, but the baldness is different from male pattern baldness.
Male Pattern baldness has been reported to be efficiently treated with Propecia.
When there is an abnormality in the immune system, it causes infection. This abnormality is due to the auto immune disorder that occurs naturally in the body. The exact reason is unknown. The body’s own immune system itself will attack the hair follicles leading to hair loss. Sometimes alopecia is present in certain medical conditions like any allergy, thyroid disorder, rheumatoid arthritis and ulcerative colitis. Heredity also plays a role in inducing baldness.
Initial signs will be formation of one or more small, coin shaped bare patches. It is more common on the scalp, but also affects other areas of the body like eye brows, eye lashes and beards. Hair falling occurs but after sometimes it may grow. There is no symptom identified but minor problem like itching may present before the formation of bald.
Alopecia areata may be the indicator of certain diseases like diabetes, asthma, atopic eczema or any auto immune disorders. There is no exact cure for this disease. The use of corticosteroids may help in suppressing the immune system. The drug is administrated directly on the hair less patches. Hair begins to grow after 4 weeks of treatment. Usage of minoxidil 5% solution twice daily also helps in the promotion of hair. Immune system is also altered by the usage of Anthralin, which promotes hair growth after 8 to 12 weeks of the treatment. Other alternatives like wigs, caps, hats also help in covering baldness.
