Alopecia areata causes hair loss and leaves bald patches on the scalp. Usually the hair will grow back, but unfortunately, the hair loss can be permanent in some cases. Treatments of alopecia are here to help hair to regrow, and they do work most of the time.
What alopecia means?
Alopecia areata basically means baldness or hair loss. There is no particular age group that this condition affects. The first signs of hair loss can begin in your twenties. Females and males are both affected, but as they grow older, mostly women suffer from this condition.
Round bald patches will develop on the scalp as you lose your hair. The scalp looks healthy and there will be no signs of scarring. You can also notice other symptoms such as scaling, redness or itching.
When hair starts to grow back, it may be white or gray. If this happens, do not be concerned, it is quite normal. Your hair will get back its natural color after a few months.
If all your hair is lost or really large areas begin to go bald, then you suffer from alopecia totalis. Alopecia universalis is where all the hair falls out, not just on the scalp, but facial and body hair too. Sometimes the nails are also affected by this condition and start to pit or get ridges.
This form of hair loss is an autoimmune disease. The immune system produces antibodies and white blood cells to protect our bodies from viruses, bacteria and many more types of germs. The affected hair roots of the bald patch are detected as a foreign area by the white blood cells, so more and more hair will fall out.
Some cases of alopecia can heal without medication in a few months, but severe types may need a little help. If you go to a hair clinic, they will examine your scalp and hair, make blood tests, and propose you a solution.
Treatment for hair loss
Specialists inject steroids directly into the bald patches, that will slow down the reactions of the immune system. The hair follicles will start to act normally allowing hair to grow back naturally. Immunotherapy is the best treatment for those who have large bald spots.
