Alopecia areata is a type of hair loss or baldness known to affect about 15 in 10,000 people. It can occur at any age and can be caused by several different causes.
What causes alopecia areata?
Alopecia areata is known to be an autoimmune disease. It occurs when the immune system attacks healthy cells in your own body. It is still not known why this occurs, but it is believed that something triggers the immune system to react against one or more body’s own tissues. Possible triggers are infection, viruses, medicine or other environmental factors. Inherit is also another factor that makes some individuals more prone to autoimmune diseases.
What Are The Symptoms Of Alopecia Areata
Typically, one or more bald patches start to appear on the scalp. They tend to be round in shape and are about the size of a large coin. They can develop pretty quickly and your hairdresser, or a relative or a close friend may be the first person to notice the bald patch/s on your scalp. Aside from the bald patch/s, the scalp tends to look healthy and there is no scarring. In some cases, mild redness, mild burning, mild scaling or a slightly itchy feeling may be experienced.
What is the best treatment for alopecia areata?
Alopecia areata is a very unpredictable condition where bald patches sometimes re-grow by themselves without treatment. Actually, when there are just one or two small bald patches, many doctors advise their patients to simply leave it alone at first.
But if the hair loss becomes more extensive, then a treatment for alopecia areata should be considered. Here are the most effective ones:
Injections of steroid are applied into the bald patches of the scalp to suppress the local immune reaction that has been occurring. This will allow the hair follicles to function normally again for hair to re-grow. This treatment for alopecia areata is recommended for one or few small-to-medium sized bald patches and are considered quite effective for patches of alopecia areata that are no too large.
Topical solutions are rubbed into the bald patches and are known to promote hair re-growth in some patients. While their success rate is not high, they may worth a try, especially in cases when there are more extensive bald patches that are not suitable for steroid infections.
Sometimes the bald patches caused by alopecia areata can grow and become more numerous. In extreme cases where all head hair is lost, scalp micropigmentation can be a solution to camouflage the symptoms. The greatest advantage of this treatment is that it can be applied within the patient’s frontal hairline, meaning if the condition recedes, the pigments are simply covered by real hair.
