Management of Frontal Fibrosing Alopecia
The most effective treatment approach for frontal fibrosing alopecia (FFA) includes 5-α-reductase inhibitors (finasteride or dutasteride) combined with intralesional corticosteroids as first-line therapy, with the goal of disease stabilization rather than hair regrowth due to the scarring nature of the condition. 1
First-Line Treatment Options
5-α-Reductase Inhibitors
- Oral finasteride (2.5 mg/day) or dutasteride (0.5 mg/day) show the highest efficacy rates (88% response rate) 2
- These medications help stabilize disease progression by reducing inflammation
- Treatment duration is typically long-term as discontinuation may lead to disease recurrence
- Important to counsel patients about potential side effects including sexual dysfunction
Intralesional Corticosteroids
- Triamcinolone acetonide (5-10 mg/mL) injected into active inflammatory areas 2
- Injections should be administered just beneath the dermis in the upper subcutis
- Treatment sessions typically every 4-6 weeks
- Most suitable for treating limited areas with active inflammation
- Skin atrophy is a common side effect at injection sites
Second-Line Treatment Options
Hydroxychloroquine
- Oral hydroxychloroquine (200-400 mg daily) may be effective in some patients
- Typically requires 6-12 months to determine efficacy
- Regular ophthalmologic monitoring is required for long-term use
Topical Treatments
- Superpotent topical corticosteroids (e.g., clobetasol 0.05% solution) applied once daily 3
- Topical calcineurin inhibitors (tacrolimus, pimecrolimus) may reduce inflammation
- Topical minoxidil 5% can be used as an adjunct therapy, particularly in cases with concurrent androgenetic alopecia
Clinical Patterns and Prognosis
FFA can be classified into three clinical patterns with different prognoses 4:
- Pattern I (Linear): Most common (48.8%), moderate prognosis
- Pattern II (Diffuse): 45% of cases, worst prognosis
- Pattern III (Double line): 6.2% of cases, best prognosis
Treatment Monitoring and Expectations
- Take baseline photographs before starting treatment
- Evaluate treatment response at 3,6, and 12 months with standardized photographs
- Success is defined as stabilization of hair loss rather than regrowth
- Treatment may need to be continued long-term to maintain stabilization
- Counsel patients that complete hair regrowth is unlikely due to the scarring nature of the disease
Important Considerations
- FFA primarily affects postmenopausal Caucasian women (mean age of presentation: 64 years) 5
- Eyebrow loss occurs in approximately 73% of patients and may be the initial presenting symptom 5
- Body hair loss can occur in 25% of cases 5
- The prevalence of FFA appears to be increasing over the past decade 5
- Hair transplantation should be considered only after disease has been stable for at least 1-2 years, with understanding that grafted hairs may still be affected by the disease process
Treatment Algorithm
- Confirm diagnosis (clinical assessment, dermoscopy, biopsy if needed)
- Assess disease activity and pattern
- Start with combination of oral 5-α-reductase inhibitor and intralesional corticosteroids for active areas
- Add topical treatments (corticosteroids, calcineurin inhibitors) for daily home use
- Consider hydroxychloroquine if inadequate response after 6 months
- Monitor every 3 months with clinical photographs
- Adjust treatment based on disease activity and side effects
The goal of treatment is disease stabilization rather than hair regrowth, and patients should be counseled accordingly about realistic expectations.
