What should be used to cover a client's hair when putting on a wig?

Using a wig cap to cover a client's hair when putting on a wig is essential for several reasons. A wig cap helps to create a smooth surface for the wig, which ensures that it fits better and looks more natural. It also keeps the client's natural hair secured and out of the way, minimizing bulk and preventing the wig from shifting during wear. Additionally, wig caps can assist in keeping the scalp covered, which can provide comfort and help with hygiene, especially if the wig will be worn for an extended period.

Other options like a scarf, bonnet, or headband do not offer the same level of effectiveness. Scarves might not provide a snug fit, making it difficult to keep hair in place, while bonnets may add unnecessary bulk. Headbands typically are not designed to hold hair down effectively under a wig, which could result in the wig not sitting properly or becoming uncomfortable for the wearer throughout the day. Overall, the wig cap is specifically designed for this purpose and is the best choice in preparing a client's hair for wig application.
