Frontal fibrosing alopecia
Clinical Classification Guidelines
Inclusion Terms
- FFA
Medical Intelligence & Overview
Frontal fibrosing alopecia (FFA) is a type of hair loss that primarily affects the frontal hairline and eyebrows. It is considered a form of scarring hair loss, which means it can cause permanent damage to hair follicles if not managed effectively. Although more common among women, especially postmenopausal women, FFA can also occur in men. Its cause remains uncertain, but it is believed to involve immune system factors and hormonal influences.
Causes & Symptoms
Clinical Causes: Possible autoimmune response where the immune system attacks hair follicles Hormonal changes, particularly related to menopause Genetic predisposition or family history Environmental factors such as UV exposure or skin irritation Potential triggers like certain hairstyles or cosmetic products
Key Symptoms: Gradual loss of hair along the frontal hairline and temples Receding hairline, often forming a band-like pattern Loss of eyebrows or other body hair Skin that appears smooth and shiny in the affected areas Presence of perifollicular erythema (redness around hair follicles) Possible scalp itching or burning sensation
Diagnostic & Treatment
Diagnosis Path: Diagnosis of FFA typically involves a clinical examination by a dermatologist, who assesses the pattern of hair loss and skin condition. A scalp biopsy may be performed to distinguish FFA from other types of alopecia, confirming the presence of follicular destruction and scarring. Trichoscopy, a non-invasive imaging technique, can also help visualize characteristic features of FFA. It is important to differentiate FFA from other hair loss conditions to enable appropriate management.
Treatment Protocols: Topical treatments such as corticosteroid creams or ointments to reduce inflammation Oral medications like corticosteroids, antimalarials, or immunosuppressants in some cases Minoxidil to promote remaining hair growth Hair transplant procedures are generally not effective due to progressive scarring Use of sunscreens and skin protection to prevent further skin damage Monitoring and follow-up with a healthcare provider to manage disease progression
