What must custom-made wigs undergo before being styled?

Custom-made wigs must undergo measuring and blocking before they are styled to ensure a proper fit and to achieve the desired shape. Measuring is essential to take accurate dimensions of the client's head, which allows the wig maker to create a wig that fits snugly and comfortably. This process considers the various contours of the head, ensuring that the final product adheres well without slipping or causing discomfort.

Blocking involves shaping the wig on a head form or block after it has been constructed. This step is crucial for achieving the intended look and style, as it allows the wig to maintain its shape and volume. By blocking the wig, stylists can manipulate the hair properly, ensuring that it looks natural and sits well on the client's head.

Other options do not prioritize the foundational aspects of creating a wig that fits correctly. Shampooing or washing a wig can be part of its maintenance but is not a prerequisite for styling. Brushing relates to the final look but is not essential before styling. Adding synthetic fibers is a method of constructing the wig but doesn't pertain to the preparatory steps necessary for proper styling.
