Advantages of Synthetic Hair:
•technological advances have produced modacrylic synthetics (like kanekalon) which are so similar in look and feel to protein-rich hair fibers that they can even fool some stylists.
•a great value; not only are they realistic, but they are less expensive than human hair wigs; they are also easier to maintain at home; shampooing with cold water will not change the style, nor will exposure to extreme humidity
•synthetic wigs tend to be made according to current styles with cut, color and texture already set; usually only needs custom trimming to be ready to wear
•color availability is almost unlimited (from natural to fantasy colors); cheapest wig styles tend to be more solid in color, while higher-quality synthetics have blended colors for natural looking hair
•synthetic colors will not fade or oxidize even after long periods in direct sunlight
•tend to be lighter in weight, thus more comfortable to wear.
Disadvantages of Synthetic Hair:
•must avoid extreme heat such as from hair dryers, hot-rollers, flat irons and curling irons
•can appear shiny and unnatural; quality and price affect how natural the hair looks; thick synthetic wigs will look unnatural on fine-haired women.
