It can be frightening to find smooth patches of skin where hair was once present. Each case of scarring alopecia can appear differently in different people, but the same upsetting process is at work. We’re taking a deep dive into this guide to scarring alopecia so we can better understand this relatively rare condition that affects some 7% of people worldwide.
What Is Scarring Alopecia?
Scarring alopecia, also known as cicatricial alopecia, is a type of hair loss that occurs when hair follicles become damaged, leading to permanent hair loss. (Often characterised by painful, itchy patches of baldness with an inflamed or scarred appearance. )While it is not always clear what causes it, it can be a result of an autoimmune disorder, inflammation, or other skin conditions.
The National Organisation of Rare Diseases tells us, “Primary cicatricial alopecia refers to a diverse group of rare disorders that destroy the hair follicle, replace it with scar tissue, and cause permanent hair loss.
“Hair loss can be gradual, without symptoms, and unnoticed for long periods. In other cases, the hair loss may be associated with severe itching, pain and burning and progress rapidly. Cicatricial alopecia occurs in otherwise healthy men and women of all ages and is seen worldwide.”
What Causes Scarring Alopecia?
The exact cause of this condition is unknown, but it is believed to be related to certain medical conditions, genetic factors, and certain medications.
WebMD tells us that common medical conditions associated with scarring alopecia include:
- Lichen planopilaris
- Bacterial or fungal infections
Certain medications, such as blood thinners, retinoids, and chemotherapy drugs, can also increase the risk of scarring alopecia.
Genetics may also play a role, as some people are more likely to develop the condition than others.
Genetic Factors and Scarring Alopecia
Certain genes are linked to the development of scarring alopecia, such as the IRF4 gene.
The IRF4 gene, also known as interferon regulatory factor 4, is a gene that is involved in the development of the immune system. It has been linked to certain forms of hair loss, including scarring alopecia. Mutations of the IRF4 gene can result in an increased risk of developing scarring alopecia, as well as other conditions such as lupus and lichen planopilaris. Research is ongoing to determine how this gene affects the development of hair loss.
One source notes, “IRF4 activity is regulated by STAT3, a signalling protein that responds to inflammatory signals and controls the expression of genes involved in the growth, development, and activation of immune system cells.
What Are The Symptoms of Scarring Alopecia?
Symptoms of scarring alopecia include patchy bald spots, broken hairs, and scarring on the scalp. Other symptoms may include an itchy, burning, or tender scalp and changes in the texture and colour of hair. These symptoms may appear gradually over a period of months or years or quite suddenly.
A Guide to Scarring Alopecia Treatments
A dermatologist or trichologist will typically diagnose traction alopecia. They will perform a physical examination of the scalp and may take a biopsy of the affected area to determine the cause and extent of the hair loss. You may require additional blood work to determine underlying medical conditions. Additionally, other tests may be performed to ascertain whether fungal infections are at work.
Treatment depends on the severity and type of scarring alopecia you have. It can be treated with topical steroids or immunosuppressants in mild cases, while more severe cases might require oral steroids or even surgery. In some cases, a combination of treatments may be necessary.
Is Scarring Alopecia Different to Traction Alopecia?
Scarring alopecia and traction alopecia are both hair loss disorders, but they differ in cause and treatment. Excessive and repetitive tension on the hair follicles, usually from hairstyles such as ponytails, braids, and buns, results in traction alopecia. On the other hand, scarring alopecia is caused by inflammation of the hair follicles due to medical conditions, medications, or genetics. While the treatments for the two conditions differ, they are both chronic disorders and can cause irreversible hair loss and baldness.
What Is The Prognosis?
The prognosis for people with scarring alopecia is largely dependent on the type and severity of the condition. Hair loss can be reversed, in some cases, with the proper treatment. In other cases, the hair loss is permanent. The most important thing is to visit a trichologist to get proper diagnosis and treatment options.
With the right treatment and management, it may be possible to minimise hair loss and, in some cases, regrow hair.
Are There Any Lifestyle Changes That Can Help Manage Scarring Alopecia?
Yes, there are certain lifestyle changes that can help manage scarring alopecia. These include avoiding excessive heat or styling tools such as blow dryers or flat irons and using high-quality, gentle hair care products.
It is also important to keep the scalp clean and hydrated by using products created specifically for people with scarring alopecia.
Additionally, it is important to pay attention to overall health and reduce stress levels. Eating a balanced diet, exercising regularly, and getting enough sleep can also help manage scarring alopecia. Finally, it is important to visit the right professional who can assess the condition and create a holistic treatment plan tailored to the individual.
