Human Hair Wigs, especially hand-tied wigs are becoming more and more popular because of their soft and comfortable cap materials and high quality knotted workmanship.
Different hair knotting methods can produce a different performance and result. The quality of the wig workmanship has a great impact on the finished products look, especially for 100% hand-tied wigs.
Single hair, single knots are considered the best method of knotting which produces a tiny knot for each individual hand-tied hair by the wig supplier. Two or three individual hairs can be single knotted at one time by speeding up the process which can be detrimental to creating a larger knot with less aesthetically pleasing finishes by the wig supplier, this is popular for full lace wigs.
Double knots wig supplier’s techniques involve knotting the hair twice to produce a double knot, which in turn provides a stronger, more robust knot. The resulting knots are, however, more visible under close inspection. This is a problem when trying to create a natural hairline and for this reason most front hairlines should be single hairs, or single knotted on a flesh tone lace material, which is also popular for full lace wigs.
Single Knots are hard to detect, but easy to shed. By contrast, double Knots are hard to shed, but easy to detect. For the advantages and the disadvantages of the two types of knots, usually wig suppliers recommend single knots at the frontal hairline 2 inches or around a perimeter of 2 inches especially for full lace wigs. This means the knots are hidden under the inside mesh (There are two pieces of mesh), and are completely invisible, giving off the impression that the hair is growing out of the scalp. This is the best method to hide the knots at present, but the procedure of processing is very complete.
Hair injection techniques refers to the method of inserting a series of hairs through a layer of polyurethane before coating the underside of the base with a single layer of liquid form polyurethane. Upon setting (or curing) the inserted hairs remain trapped between the two transparent layers. Hair injection is a relatively new method of hair attachment, becoming increasingly popular due to its natural appearance, knot free style and is used by wig suppliers. This workmanship is usually asked for by Skin top wigs / French top wigs.
