Detailed answer

To prevent a rash from wearing wool, it is recommended to apply a barrier cream, such as a zinc oxide-based cream, to create a protective layer between the skin and the wool fabric. This can help reduce skin irritation and itching. Additionally, wearing a breathable layer, such as a cotton or silk garment, underneath the wool clothing can provide an extra barrier and help prevent direct contact between the wool and the skin. This can help minimize the risk of developing a rash or skin irritation from wool. It's also important to choose high-quality, hypoallergenic wool that has been properly processed to reduce potential irritants. If the rash persists or worsens, it is advisable to consult a dermatologist for proper diagnosis and treatment.
