Solutions for Scarring Hair Loss
Scarring hair loss, also known as cicatricial alopecia, refers to a group of conditions in which inflammation or injury damages the hair follicle and replaces it with scar tissue. Unlike many common forms of hair loss, damage to affected follicles may be permanent.
There are several possible causes, including inflammatory, autoimmune, infectious and traumatic conditions. Because different forms of scarring alopecia can look similar, early assessment by a GP or dermatologist is important when persistent scalp inflammation, patchy hair loss, redness, scaling or scarring is present.
This article provides an overview of the main causes, symptoms and treatment pathways and explains when specialist assessment may be appropriate.
What Causes Scarring Hair Loss?
It can arise from a variety of underlying causes, including autoimmune disorders, inflammatory conditions, and physical trauma. Here are some of the common factors that contribute to this condition:
- Autoimmune disorders: Certain autoimmune diseases, such as lupus erythematosus, lichen planopilaris, and frontal fibrosing alopecia, can trigger an immune system attack on the hair follicles, leading to inflammation, scarring, and permanent hair loss.
- Inflammatory conditions: Chronic inflammatory skin conditions like folliculitis decalvans, dissecting cellulitis of the scalp, and acne keloidalis nuchae can cause inflammation and subsequent scarring of the hair follicles.
- Physical trauma: Injuries to the scalp, such as burns, radiation therapy, or repeated traction from hairstyles like tight braids or ponytails, can damage the hair follicles and lead to scarring.
- Genetic predisposition: Some forms of scarring hair loss, like certain types of lichen planopilaris, may have a genetic component, making individuals more susceptible to developing the condition.
- Infections: Bacterial or fungal infections of the scalp, if left untreated, can cause inflammation and scarring, leading to permanent hair loss.
It’s important to note that in many cases, the exact cause remains unknown, making it a challenging condition to diagnose and treat effectively.
Different Types of Scarring Hair Loss
It can manifest in various forms, each with its own unique characteristics and underlying causes. Here are some of the most common types:
- Lichen planopilaris (LPP): This is an autoimmune disorder that primarily affects the scalp, causing inflammation, scarring, and permanent hair loss. LPP can occur in localised patches or diffuse patterns, and it’s more common in women.
- Frontal fibrosing alopecia (FFA): This type of scarring hair loss primarily affects the frontal hairline and eyebrows, causing progressive recession and scarring. FFA is more prevalent in postmenopausal women.
- Folliculitis decalvans: This inflammatory condition is characterised by painful, pus-filled bumps on the scalp that can lead to scarring and permanent hair loss. It’s often associated with bacterial infections.
- Dissecting cellulitis of the scalp: This rare condition involves the formation of abscesses and sinus tracts in the scalp, leading to scarring and hair loss. It’s more common in men and can be associated with underlying medical conditions.
- Acne keloidalis nuchae: This type of scarring hair loss primarily affects the back of the scalp and nape of the neck, causing firm, keloid-like lesions and subsequent hair loss. It’s more common in men of African descent.
- Central centrifugal cicatricial alopecia (CCCA): This form of scarring hair loss typically starts at the vertex (top) of the scalp and spreads outward in a circular pattern. It’s more prevalent in women of African descent.
Symptoms
Early recognition of the symptoms is essential for prompt diagnosis and treatment, as it can help prevent further hair follicle damage and potential scarring. Here are some common symptoms to watch out for:
- Patchy hair loss: One of the earliest signs is the appearance of smooth, bald patches on the scalp, often accompanied by redness, inflammation, or scaling.
- Itching or burning sensation: Many forms are accompanied by an itchy or burning sensation on the affected areas of the scalp, which can be a sign of inflammation.
- Scarring or roughness: As the condition progresses, the affected areas of the scalp may develop a rough, scarred texture, indicating permanent hair follicle damage.
- Pustules or lesions: In some types of scarring hair loss, such as folliculitis decalvans, you may notice the presence of pus-filled bumps or lesions on the scalp.
- Receding hairline or eyebrow thinning: Conditions like frontal fibrosing alopecia can cause progressive recession of the frontal hairline or thinning of the eyebrows.
- Increased shedding: While shedding is a normal part of the hair growth cycle, excessive shedding or thinning of the hair in specific areas can be an early sign of scarring hair loss.
Diagnosis and Treatment Options for Scarring Hair Loss
Diagnosing scarring hair loss can be challenging, as it often requires a combination of clinical evaluation, medical history, and specialised tests. Here’s an overview of the diagnostic process and available treatment options:
Diagnosis
- Physical examination: A dermatologist may examine the scalp and hair closely for signs of inflammation, scarring or follicle damage.
- Medical history: Your dermatologist will ask about your medical history, including any autoimmune disorders, skin conditions, medications, or recent trauma to the scalp.
- Trichoscopy: This non-invasive technique involves using a specialised handheld device or dermatoscope to examine the scalp and hair follicles in greater detail.
- Biopsy: In some cases, a small sample of scalp tissue may be taken (biopsy) for further analysis under a microscope to determine the specific type of scarring hair loss and underlying cause.
- Blood tests: Depending on the suspected cause, assessment may include medical history, trichoscopy, scalp biopsy or blood tests.
Treatment Options
The treatment approach for scarring hair loss depends on the specific type, underlying cause, and severity of the condition. Here are some common treatment options:
- Medications: Treatment is normally guided by a dermatologist and depends on the particular type of scarring alopecia and whether the condition is still active.
- Topical treatments: Treatment may include anti-inflammatory, antimicrobial or immune-modulating medicines depending on the diagnosis. In some circumstances, topical treatments may also be recommended.
- Phototherapy: Exposure to specific wavelengths of light, such as ultraviolet or excimer laser, can help reduce inflammation and promote hair regrowth in certain types of scarring hair loss.
- Surgical procedures: Hair restoration surgery may occasionally be considered after the underlying condition has been inactive and stable for an appropriate period. Suitability requires specialist assessment because active scarring alopecia can affect transplanted follicles.
- Combination therapy: In many cases, a combination of different treatments, such as medications, topical treatments, and phototherapy, may be used to achieve optimal results.
Self-Care and Complementary Approaches
Lifestyle measures and gentle scalp care may support general hair and scalp health, but they cannot reverse follicles that have already been destroyed by scarring alopecia. Supplements, essential oils, acupuncture and other complementary therapies have limited evidence for treating scarring alopecia specifically and should not delay medical assessment where an inflammatory or autoimmune condition is suspected.
- avoid tight hairstyles and repeated traction
- use gentle hair/scalp care
- manage diagnosed underlying conditions
- stop smoking
- maintain balanced nutrition.
It’s important to remember that while natural remedies and alternative treatments may offer potential benefits, they should not be considered a substitute for conventional medical treatments prescribed by your dermatologist.
When hair loss is associated with established scalp scarring, previous injury, surgery or another reconstructive concern, further specialist assessment may sometimes be appropriate. Miss Anca Breahna is a Consultant Plastic Surgeon with experience in reconstructive surgery; however, medical diagnosis and treatment of active scarring alopecia is generally led by dermatology.
Lifestyle Changes to Support Hair Regrowth
Medical treatments and therapies are essential for managing the condition, but adopting a healthy lifestyle can also play a role in supporting hair regrowth and preventing further scarring. Here are some lifestyle changes you can consider:
- Hydration: Adequate hydration is important for overall health, including hair health. Aim to drink at least eight glasses of water per day and incorporate water-rich fruits and vegetables into your diet.
- Gentle hair care: Avoid excessive tension, heat, or chemical treatments on your hair, as these can damage the hair follicles and potentially contribute to scarring hair loss. Opt for gentle hair care products and techniques, and avoid tight hairstyles that pull on the hair.
- Scalp protection: Protect your scalp from physical trauma, excessive sun exposure, and environmental pollutants, as these can contribute to inflammation and scarring. Wear protective headgear when necessary and use gentle, fragrance-free hair products.
- Quit smoking: Smoking has been linked to various hair and scalp conditions. Quitting smoking can improve overall health and potentially support hair regrowth.
- Exercise regularly: Regular physical activity can improve blood circulation, reduce stress, and promote overall well-being, which can indirectly support hair health.
- Manage underlying conditions: If you have an underlying medical condition, such as an autoimmune disorder or hormonal imbalance, working closely with your healthcare provider to manage these conditions can help reduce the risk of scarring hair loss or prevent further progression.
FAQs about Causes and Treatment for Scarring Hair Loss
