Today's better quality synthetic wigs are virtually indistinguishable from human hair, except to the most practiced eye. Synthetic wigs are easier to care for and lower priced. The monofilament fiber "hair" used to make synthetic wigs has "memory" which means it maintains its wave or curl, texture and volume, requiring minimal upkeep. Synthetic wigs, however, are not designed to accept a permanent wave or color change and can be permanently damaged by the use of curling irons, blow dryers or hot rollers.
