Alopecia circumscripta is a typical autoimmune condition that frequently causes irregular hair loss. The majority of the time, hair thinning occurs in little patches about the size of a quarter. Alopecia circumscripta may just cause a few patches, but it can also affect larger regions of the scalp.

White blood cells that target the cells in hair follicles give rise to the condition by causing them to constrict and drastically slow down hair development. It is unclear why the immune system of the body specifically targets hair follicles in this manner.

Currently, alopecia circumscripta is incurable, although there are several forms of treatment that doctors might recommend to enhance the growth of new hair.


The most prominent symptom of alopecia circumscripta is patchy hair loss. Hair flakes the size of small coins begin to shed, usually from the scalp. But every place where hair grows might be impacted, even the beard and eyelashes.

A few days or a few weeks may pass before there is a noticeable hair fall. Before hair loss, there may be burning or itching in the area. Because the hair follicles are not damaged, if the inflammation in the follicles goes down, new hair can form.

People who just lose a few patches of hair frequently make a full recovery without receiving any kind of treatment.


Alopecia circumscripta is typically simple for doctors to identify by looking at symptoms. They could examine hairs from the afflicted areas under a microscope and evaluate the extent of hair loss.

The doctor can undertake the following if, after a preliminary clinical examination, they are unable to make a diagnosis:


Alopecia circumscripta has no known cure. However, there are therapies you can try that may be able to prevent more hair loss or hasten the rate at which hair regrows. Since the illness is unpredictable, it could take a lot of trial and error before you find a treatment that works for you. It’s crucial to keep in mind that treatment isn’t always effective. Even after receiving treatment, some people may still have hair loss.

Here are some of the potential remedies:

  • Topical agents
  • Injections
  • Oral treatments
  • Laser and Light therapy
  • Natural treatment

Each treatment’s efficacy will differ from one person to another. Certain individuals won’t require treatment because their hair will regrow on its own. In other instances, though, after potentially utilizing every available therapeutic option, patients won’t experience improvement.
