Hair loss occurs because the hair is affected by inflammation. However the cause of inflammation is still not known, but it is believed that the body own defence system (immune system) that usually protects the body against infections and others health issues, may attack the growing hair. The reason behind this action is still not understood.
Alopecia areata is not contagious, and there is no link between food or vitamin deficiencies. Stress rarely appears to trigger the condition. It is estimated that there is about 20% of people with alopecia areata that have a family background of the disease.
Symptoms of alopecia areata
An individual suffering from alopecia areata may experience a tingling sensation in the scalp; the condition can upset you as the bald area cannot be disguised by hairstyle.
If you have a patch on your eyelashes then this may become sore due to dust particles, particularly in the wind.
Treatment of alopecia areata
People with the mild condition does not require treatment as the chances fo hair growth is high without the treatment. Some treatments are available that help induces hair growth though none can alter the overall course of the hair loss condition.
The hair loss treatments may include:
Steroid Creams- These creams are meant to be applied on bald patches twice daily for a restricted time.
Local steroid injections-These injections are injected directly into the scalp and eyebrows. The treatment is one of the most effective approaches for small bald patches. Injections can be injected every four to six week by a dermatologist. The hair loss treatment should be stopped once regrowth is achieved. You may develop a small simple at the injection site which is not the thing to worry as this disappears with time. Caution should be exercised while injection into eyebrows as excess medication can result in glaucoma (an eye condition defined by a raised pressure in the eyeballs).
Steroid tablets-large dose of steroid tablets are given for regrowth of hair. The treatment is not as effective as injections as there are chances of recurrence of disease after stopping the treatment.
