Hand-Tied: Hand-tied wigs are individual hairs, hand-sewn to thin stocking cap. Though more expensive, hand-tied wigs look more natural, as if the hair is naturally growing right from your own scalp; they are more comfortable too.
Machine-Made: Weft (or machine-made) wigs are less expensive. The hair is sewn by machine into a vertical-lined cap. The hair is more difficult to part, hair lines can be seen if the wind blows, and the base is heavier due to the added fabric in the cap’s design.
