Cicatricial Alopecia
Hair loss can be a distressing experience, but understanding the underlying causes and potential treatments can provide some relief. One particularly challenging type of hair loss is cicatricial alopecia, also known as scarring alopecia. This condition involves the destruction of hair follicles, leading to permanent hair loss. In this article, we will delve into the symptoms, causes, risk factors, types, and treatment options for cicatricial alopecia.
What is Cicatricial Alopecia?
Cicatricial alopecia refers to a group of rare disorders that destroy hair follicles and replace them with scar tissue, resulting in permanent hair loss. Unlike non-scarring alopecia, where hair follicles remain intact, cicatricial alopecia involves irreversible damage.

The symptoms of cicatricial alopecia can vary significantly from one individual to another. Common symptoms include:
- Redness and Inflammation: The scalp often appears red and inflamed.
- Itching or Burning: Patients may experience itching, burning, or pain in the affected area.
- Pustules or Blisters: Small bumps or blisters can form on the scalp.
- Scaling: Flaky skin may be present.
- Permanent Hair Loss: The most significant symptom is the permanent loss of hair in the affected area.
Causes of Cicatricial Alopecia
The exact cause of cicatricial alopecia remains unknown. However, it is believed to involve an inflammatory process that destroys hair follicles. Various factors can contribute to this inflammation, including:
- Autoimmune Disorders: Conditions such as lupus and lichen planopilaris can trigger an immune response that attacks hair follicles.
- Infections: Bacterial, viral, and fungal infections can contribute to the development of cicatricial alopecia.
- Genetic Predisposition: A family history of autoimmune disorders or cicatricial alopecia may increase the risk.
- External Factors: Trauma, burns, and radiation therapy can damage hair follicles and lead to scarring alopecia.
Risk Factors for Cicatricial Alopecia
Several risk factors can increase the likelihood of developing cicatricial alopecia:
- Gender: Some types, like central centrifugal cicatricial alopecia (CA), are more common in women, particularly African American women.
- Age: While cicatricial alopecia can occur at any age, certain types are more prevalent in middle-aged adults.
- Ethnicity: Certain ethnic groups, such as African Americans, may be at a higher risk for specific types of cicatricial alopecia.
Types of Cicatricial Alopecia
Cicatricial alopecia encompasses various subtypes, each with distinct characteristics:
Lichen Planopilaris (LPP)
LPP is an inflammatory condition that affects the scalp and other hair-bearing areas. It often presents as patches of hair loss with itching and redness.
Frontal Fibrosing Alopecia (FFA)
FFA primarily affects postmenopausal women, causing a receding hairline and eyebrow loss. It is considered a variant of LPP.
Central Centrifugal Cicatricial Alopecia (CCCA)
CCCA predominantly affects African American women, beginning at the crown and spreading outward. It may be associated with hairstyling practices.
Dissecting Cellulitis
This condition involves painful nodules and abscesses on the scalp, leading to scarring and hair loss.
Diagnosis of Cicatricial Alopecia
Diagnosing cicatricial alopecia requires a thorough evaluation by a dermatologist. The diagnostic process typically includes:
- Clinical Examination: The dermatologist will examine the scalp and review medical history.
- Scalp Biopsy: A small sample of the affected scalp is taken and examined under a microscope to identify inflammation and scarring.
- Blood Tests: Blood tests may be conducted to rule out underlying autoimmune or infectious conditions.
Treatment Options for Cicatricial Alopecia
Treating cicatricial alopecia can be challenging, and the primary goal is to halt the progression of the disease. Treatment options include:
Corticosteroids
Corticosteroids are often the first line of treatment. They can be administered topically, orally, or through injections to reduce inflammation and prevent further follicle damage.
Immunosuppressive Drugs
Medications such as cyclosporine, methotrexate, and mycophenolate mofetil can suppress the immune response and help control inflammation.
Antibiotics
In cases where bacterial infections are suspected, antibiotics may be prescribed to address the underlying disease.
Antimalarial Drugs
Hydroxychloroquine, an antimalarial drug, has shown effectiveness in reducing inflammation in certain types of cicatricial alopecia.
Hair Transplantation
Hair transplantation may be an option for patients with stable cicatricial alopecia. However, before considering this procedure, it is crucial to ensure that the inflammatory process is under control.
Complications of Cicatricial Alopecia
If left untreated, cicatricial alopecia can lead to several complications:
- Permanent Hair Loss: The destruction of hair follicles results in irreversible hair loss.
- Psychological Impact: Hair loss can significantly impact self-esteem and mental well-being.
- Secondary Infections: Inflammation and scarring can create an environment conducive to secondary infections.

Understanding the distinction between cicatricial alopecia and non-scarring alopecia is essential:
- Cicatricial Alopecia: Involves the permanent destruction of hair follicles, leading to irreversible hair loss.
- Non-Scarring Alopecia: Hair follicles remain intact, and hair loss is often reversible with appropriate treatment.
Conclusion
Cicatricial alopecia is a complex and challenging condition that requires early diagnosis and intervention to prevent permanent hair loss. By understanding the symptoms, causes, risk factors, and treatment options, individuals affected by this condition can take proactive steps to manage it effectively. Consulting with a dermatologist is crucial for accurate diagnosis and tailored treatment plans. While cicatricial alopecia may be a daunting diagnosis, advancements in medical research offer hope for better management and improved quality of life for those affected.
