Baseball caps are commonly worn in the United States, in part for photoprotection. Public health efforts to prevent skin cancers recommend wide-brimmed hats over baseball caps owing to caps’ incomplete coverage for face, neck, and ears; however, to our knowledge, their relative efficacy for scalp photoprotection has not been investigated. We report a case of focal chronic photodamage and actinic keratoses on a patient’s alopecic scalp despite his adherence to baseball cap use for photoprotection.
