Frontal fibrosing alopecia (FFA) typically presents with band-like scarring alopecia in the frontal and temporal hairline along with eyebrow loss. Although this type of hair loss is being seen with increased frequency worldwide, the etiology of the condition is unknown. Studies have suggested a potential environmental role with moisturizers and sunscreens being possible triggers. Herein, we present a 42-year-old woman with a biopsy-proven diagnosis of frontal fibrosing alopecia. In addition to the typical pattern, she also had a striking linear patch of hair loss along her central part. This was an area where she regularly applied sunscreen for many years. Although a causative role for sunscreen ingredients in the development of FFA has not been proven, the evidence accumulated thus far, including our suggestive case, substantiates the need for further study. Additionally, increasing awareness of this potential effect leading to appropriate counseling regarding cessation of possible triggers may be critical for the prevention of further hair loss.
