Actinic keratoses on the balding head of an older man Actinic keratoses on the balding head of an older man. Hair loss results in less natural sun protection and is a risk factor for skin cancers on the scalp. The visible and palpable actinic keratoses were treated with cryotherapy. (Courtesy of Richard P.
