Wearing a wig generally does not cause allergies, but those with more sensitive constitutions should not wear them. In addition, wigs will have a certain impact on the skin of the head. People who originally suffered from skin diseases such as dermatitis and eczema may make the condition worse, and wait until the skin disease is completely cured. In addition, the summer weather is hot and wearing a wig is not good for sweating. Therefore, the wearer should choose a good quality wig when choosing a wig. It is best to wear a breathable mesh, and it is not suitable to wear it for a long time.
