Human Hair Wig Maintenance Tips: Sleeping with the wig on is not recommended. This is to avoid tangling of the wig and breakage of the hair. Always wash your wig with a mild shampoo and conditioner, and never use any harsh chemicals on it. Always naturally air dry your wig. Avoid using heating equipment to dry your wig. To avoid tangling, brush your wig gently before and after, with the help of a wide tooth comb. Store your wig in a dry and cool place, away from sunlight and heat.
