As a rule, wigs are constructed in a basic way across all manufacturers, distributors and sellers. As a rule, wigs are designed to incorporate some of all of the most popular features including utilization of special fibers at, or near, the base of the wig cap, to add body to the wig, without tangling or styling.
The special fibers provide natural life, height and appropriate volume like you might see in a natural head of hair.
Due to the ongoing advancements in the wig industry, the days of the hard wigs caps have changed into a variety of soft or no cap options.
Depending on the manufacturer and the model, wigs may have a totally capless base, which is completely open wefts pieced over a base, but with no closed sections.
The result is a much cooler and lighter wig. Although wearing a wig is still going to feel somewhat like wearing a head covering, wigs have evolved dramatically so that the comfort factor of the past is long gone.
The new wigs also might have a basic soft cap construction which may or may not include hand tied, lace front or natural skin hairlines for a more natural appearance.
This means the hairlines are carefully hand stitched with individual hair or hairline fibers or created to simulate natural skin such as might be found on a real hairline.
