A Synthetic wig is sometimes referred to as a Modacrylic wig. The most appealing aspect to synthetic hair is it can often be worn right out of the box with little or no styling. The fibre used has "memory" for wave, curl and volume which lets hair bounce back into place with minimal effort -- the curl pattern is permanently set.
It can even hold up in bad weather and can guarantee no drooping or frizzing. Synthetic hair is strands of fibres that are manufactured to look and to feel like natural hair and is usually is made out of kanekolon or toyokalon, which are two types of synthetic fibres. Synthetic wigs can be hand washed with the shampoo & conditioner designed for Synthetic fibre and should be left to dry naturally, no heat appliance can be used on Synthetic wigs.
