Despite a significant increase in reported cases of frontal fibrosing alopecia (FFA) in literature, discussion about the possible role of environmental factors, instruction for diagnosis and guideline for treatment, are limited. The review aims to provide a detailed synthesis of this condition that could be used by clinicians in their practise. Whether single-centre or multi-centre, studies of more than 60 cases less than 5 years old were mainly taken into consideration. Results obtained were that FFA affects mainly postmenopausal Caucasian women; the most common comorbidities are hyperlipidaemia, arterial hypertension, osteoporosis, hypothyroidism, depression, alongside dermatological disorders such as atopic dermatitis, rosacea, seborrheic dermatitis and androgenetic alopecia. Autoimmune, genetic, hormonal (e.g. estrogen deficiency, pregnancy, lactation, HRT and raloxifene) and environmental (e.g. daily use of facial sunscreens and less frequent use of hair dyes and shampoo) hypotheses were proposed for pathogenesis, as well as association with various predisposing factors (patient's health-social profile, disease's history and comorbidities). Clinical presentation of FFA can be divided into 3 specific patterns, each with a different prognosis. Diagnosis is usually made clinically with the use of trichoscopy; however, scalp biopsy remains the gold standard. The condition is regarded as a variant of lichen planopilaris (LPP) due to the similarity of the prominent histopathological findings, but the clinical image is distinct and therapeutic options vary. 5α-reductase inhibitors, intralesional steroids, and hydroxychloroquine provide the highest level of evidence for the treatment of FFA. The conclusion is that a better understanding of the disease is crucial for proper disease management.
