Human Hair quality Lace Wigs are made of human hair often mixed with premium quality heat resistant fiber. Recently some manufacturers have resorted to mixing human hair with heat resistant hair, because the features of the hair do not change significantly and make the product more affordable to customers. This has been also a result of the price of raw human hair rising up for the last 2 years. Customers should beware when purchasing this human hair quality product because even though it can be curled and straightened, it cannot be died/colored. Also be cautious of not overpaying for human hair quality products as they should be comparatively cheaper than 100% human hair products. The most popular manufacturer of this quality Lace wigs is Janet Collection. Their products carry the name Encore Full Lace wigs and are a blend of human hair and heat resistant fibers. The hair texture of Encore wigs feels soft and human like to the touch. The hair can be styled with curling or flat irons.
