Causes of Alopecia Areata
Alopecia areata is believed to be an autoimmune disorder, where the immune system mistakenly attacks the hair follicles, causing them to shrink and eventually stop producing hair. Genetics may also play a role, as alopecia areata tends to run in families. Additionally, stress and certain medical conditions like psoriasis may trigger alopecia areata.
Types & Symptoms of Alopecia Areata
There are three main types of alopecia areata which are patchy, alopecia totalis (total hair loss on the scalp), and alopecia universalis (total hair loss on the body).
- The most common symptom is patchy hair loss, which can affect the scalp, beard, eyebrows, and eyelashes. Before hair loss, some people may experience burning or itching in the area. The affected areas may be smooth or have some scaling, and in some cases, the skin may become slightly pink or reddish. Alopecia Areata may also affect the nails, causing dents and brittle nails.
Treatment Options for Alopecia Areata
Having bald patches can greatly impact a person’s quality of life, which is why effective treatments are developed to help with this condition. These treatments aim to stimulate hair growth, reduce inflammation, or suppress the immune system’s response.
Topical corticosteroids
Used to reduce inflammation and promote hair growth.
Steroid injections
In more severe cases, injections of corticosteroids directly into the scalp may be necessary.
Immunotherapy
Another treatment option is topical immunotherapy, which involves applying a chemical named diphencyprone (DPP) once a week to stimulate the immune system.
UV light treatment
A non-scarring but less effective method that can help hair re-grow faster.
In some cases, hair growth may occur naturally without any treatment, but it can take several months or even years. Wearing wigs or other hairpieces is also an option for those who are experiencing significant hair loss.
