Sources: 2. Developments: 2. Medical experts in Argentina and Brazil have highlighted the dermatological risks associated with winter weather conditions, specifically regarding scalp and skin health. In Argentina, dermatologists noted that cold temperatures, indoor heating, and hot showers can dry the scalp, increasing sebum production and the growth of Malassezia, which triggers dandruff. Experts recommended shampoos containing selenium sulfide, zinc pyrithione, or salicylic acid, while emphasizing stress management and proper moisturization. In Brazil, reports expanded on these risks, noting that low humidity and wind exacerbate dandruff and seborrheic dermatitis. Additionally, experts pointed out that the lack of sebaceous glands makes lips particularly vulnerable to dehydration, scaling, and cracking. Recommendations for lip care include high water intake and the use of protective repair products, while dandruff management may require antifungal shampoos containing cyclopirox olamine or piroctone olamine. ## Timeline ### 2026-08-31: Winter weather increases risks of dry lips and dandruff Cold winter weather and low humidity can increase lip dryness and dandruff due to changes in skin hydration and scalp microbiota.
