Detailed answer

To prevent a rash from wearing a hat, follow these steps. Firstly, make sure to keep your scalp clean and dry by washing it regularly with a mild shampoo and thoroughly drying it before putting on a hat. Secondly, choose hats made of breathable fabrics like cotton or linen, as they allow air circulation and reduce the likelihood of sweat getting trapped against your skin. Avoid synthetic materials that can cause irritation and perspiration buildup. Lastly, refrain from sharing hats with others, as this can transfer bacteria, fungi, or other potential causes of rashes. By following these preventive measures, you can minimize the risk of developing a rash from wearing a hat.
