Detailed answer

Hair and scalp actinic keratoses are primarily caused by long-term sun exposure and damaging UV radiation. Allergies to skincare products, on the other hand, result from an immune reaction to certain ingredients within the products. While allergies can lead to various skin reactions such as redness, itching, or rashes, they do not directly cause actinic keratoses. However, it is worth noting that certain skincare products may contain ingredients that can sensitize the skin to UV radiation, increasing the risk of developing actinic keratoses. Therefore, it is important to choose skincare products that are appropriate for your skin type and avoid prolonged sun exposure without protection to prevent actinic keratoses.
