Lichen planopilaris (LPP) is a rare inflammatory condition that affects the scalp, leading to hair loss. It is a variant of lichen planus, which can affect the skin, nails, and mucous membranes. LPP is characterized by inflammation and destruction of hair follicles, resulting in permanent hair loss if left untreated. This article explores the best treatment options for LPP, highlighting their effectiveness, potential side effects, and the latest research developments.
Understanding Lichen Planopilaris
What is Lichen Planopilaris?
Lichen planopilaris is an autoimmune disorder where the body’s immune system attacks hair follicles, causing inflammation. This leads to scarring alopecia, where scar tissue replaces hair follicles, making hair regrowth impossible. LPP typically presents with symptoms such as itching, burning, and tenderness of the scalp, along with noticeable hair loss.
Causes and Risk Factors
The exact cause of LPP is unknown, but it is believed to be an autoimmune reaction. Several factors may contribute to its development, including:
Genetics: A family history of autoimmune diseases may increase the risk.
Environmental Triggers: Infections, stress, and certain medications may trigger LPP.
Immune System Dysfunction: Abnormal immune responses can lead to follicular inflammation.
Diagnosis of Lichen Planopilaris
Clinical Examination
Diagnosis of LPP often begins with a clinical examination by a dermatologist, who will look for characteristic signs such as redness, scaling, and follicular hyperkeratosis (excess keratin around hair follicles).
Scalp Biopsy
A definitive diagnosis is typically made through a scalp biopsy, where a small sample of scalp tissue is examined under a microscope. This can reveal the presence of lymphocytic inflammation around hair follicles, a hallmark of LPP.
Treatment Goals
The primary goals of treating LPP are to:
Reduce Inflammation: Alleviate the inflammatory response to prevent further damage to hair follicles.
Manage Symptoms: Control symptoms such as itching and burning.
Prevent Further Hair Loss: Halt the progression of the disease to preserve remaining hair.
Promote Hair Regrowth: Stimulate hair regrowth where possible, though this is often challenging due to scarring.
Topical Treatments
Topical Corticosteroids
Topical corticosteroids are often the first line of treatment for LPP. They help reduce inflammation and suppress the immune response.
Application: Usually applied directly to the affected areas of the scalp.
Effectiveness: Can be effective in reducing inflammation and slowing disease progression.
Side Effects: Prolonged use can lead to skin thinning, irritation, and other side effects.
Topical Calcineurin Inhibitors
Topical calcineurin inhibitors, such as tacrolimus and pimecrolimus, are alternatives to corticosteroids, especially for long-term use.
Application: Applied to the scalp, often in the form of a cream or ointment.
Effectiveness: Can reduce inflammation and are useful for patients who cannot tolerate corticosteroids.
Side Effects: Possible side effects include local irritation and a burning sensation upon application.
Systemic Treatments
Oral Corticosteroids
For more severe cases of LPP, oral corticosteroids may be prescribed to quickly reduce inflammation.
Dosage: Typically prescribed in a tapering dose to minimize side effects.
Effectiveness: Highly effective in controlling inflammation and halting hair loss.
Side Effects: Long-term use can lead to significant side effects, including weight gain, osteoporosis, and increased susceptibility to infections.
Immunosuppressive Agents
Immunosuppressive agents, such as methotrexate, cyclosporine, and mycophenolate mofetil, are used to modulate the immune system.
Usage: Often used in patients who do not respond to corticosteroids or who require long-term treatment.
Effectiveness: Can be effective in controlling inflammation and preventing further hair loss.
Side Effects: Potential side effects include liver toxicity, kidney damage, and increased risk of infections.
Antimalarial Drugs
Hydroxychloroquine
Hydroxychloroquine is an antimalarial drug that has immunomodulatory effects, making it useful in treating autoimmune conditions like LPP.
Dosage: Usually taken orally in tablet form.
Effectiveness: Can be effective in reducing symptoms and slowing disease progression.
Side Effects: Possible side effects include gastrointestinal upset, retinal toxicity (rare), and skin rashes.
Emerging Treatments
Janus Kinase (JAK) Inhibitors
JAK inhibitors, such as tofacitinib and ruxolitinib, are a newer class of drugs that target specific pathways in the immune response.
Usage: Typically used off-label for LPP, as they are primarily approved for other autoimmune conditions.
Effectiveness: Early studies suggest they may be effective in reducing inflammation and promoting hair regrowth.
Side Effects: Potential side effects include increased risk of infections, liver enzyme abnormalities, and blood clots.
Low-Level Laser Therapy (LLLT)
Low-level laser therapy involves using red or near-infrared light to stimulate hair follicles and reduce inflammation.
Application: Typically administered through a device worn on the scalp.
Effectiveness: Some studies suggest it may help improve hair density and reduce symptoms.
Side Effects: Generally well-tolerated, with minimal side effects reported.
Supportive Treatments and Lifestyle Modifications
Scalp Care
Proper scalp care can help manage symptoms and improve overall scalp health.
Gentle Cleansing: Use mild shampoos to avoid irritation.
Moisturizing: Keep the scalp moisturized to reduce itching and scaling.
Stress Management
Stress can exacerbate autoimmune conditions, so managing stress is crucial.
Techniques: Practices such as yoga, meditation, and mindfulness can help reduce stress levels.
Professional Support: Consider therapy or counseling to address chronic stress or anxiety.
Case Studies and Patient Experiences
Case Study 1: Successful Treatment with Hydroxychloroquine
A 45-year-old female patient diagnosed with LPP experienced significant improvement after starting hydroxychloroquine. Within six months, her symptoms of itching and burning subsided, and further hair loss was prevented.
Case Study 2: Combination Therapy with Topical and Oral Corticosteroids
A 38-year-old male patient with severe LPP showed remarkable improvement with a combination of topical and oral corticosteroids. The inflammation reduced significantly, and disease progression was halted.
Research and Future Directions
Ongoing research aims to better understand the pathogenesis of LPP and develop more targeted treatments. Advances in immunology and genetics may pave the way for personalized medicine approaches, offering more effective and tailored therapies for patients with LPP.

Conclusion
Lichen planopilaris is a challenging condition that requires a multifaceted approach to treatment. While there is no cure, various treatment options can effectively manage symptoms, reduce inflammation, and prevent further hair loss. Topical and systemic treatments, along with emerging therapies, offer hope for patients struggling with this condition. Collaborative care involving dermatologists, primary care physicians, and mental health professionals can provide comprehensive support for individuals with LPP, enhancing their quality of life and overall well-being.
