The Complete Handbook of Wig Caps

Chapter 1: Understanding Wig Caps

A wig cap is not an afterthought. It is the engineered foundation upon which an entire hair replacement system rests. It is the structure that bears the weight of the hair, holds the shape against the scalp, provides the internal environment for the skin, and establishes the realistic movement of the hair at the hairline. Purchasing a wig based solely on the length, color, or style of the hair is equivalent to buying a car because of the paint job; the cap is the chassis, and its quality dictates every aspect of performance, comfort, and longevity.

This chapter begins with the fundamental question: what exactly is a wig cap? At its most basic, it is a one-piece skullcap-shaped substrate, usually made from a combination of fabrics, meshes, or synthetic materials, onto which hair fibers are attached or into which they are hand-tied. This substrate conforms to the head, holding the attached hair in a predetermined distribution and orientation. It is the part of the wig that touches the skin, and it is the part that you cut, alter, and shape to properly fit your specific client's head. When a wig fails, in nine out of ten cases, the root of the problem lies in the cap. The hair fibers themselves are durable; it is the cap's foundation, its seams, its elasticity, and its lace that experience the most significant stress during wear, removal, and cleaning.
