A Remy human hair wig has an in-tact cuticle layer, which is the outer layer of each hair strand that lays like shingles on a roof (all traveling in the same direction). This results when the hair is gathered and kept in bundles with all the hair going in the same direction. This means the cuticle is all going in the same direction in the bundle, making this type of wig the very best quality.Human hair wigs can be expensive if they are 100% remy human hair, but are well worth the investment! Human hair blended wigs and synthetic wigs are less expensive, but are not as high in quality.
