Lace wigs fall into 3 general groups: Full Lace, Front Lace and Half Lace.
Some Lace wigs are made with Swiss lace (the softest and the finest) and some with French lace (harder and more resistant).
Front Lace wigs have lace at the forehead extending usually from ear to ear. Therefore Front Lace wigs cannot be pulled in a high pony tail unlike Full Lace Wigs. Front lace wigs will give you a natural hairline in the front. This means the hair can be parted anywhere throughout the front of the unit. This cap style only has to be glued down or taped in the front and is ideal for women that never want to wear their hair in up-dos or high ponytails or have hair thinning or other medical conditions.
Full Lace wigs are wigs where the amount of lace allows you to put the wig in a high ponytail. Full Lace wig construction may vary from one manufacturer to another. Usually custom made Full Lace wigs have lace all over. Full lace wigs manufactured in bulk usually come in one standard size-one size fits all and that is why they only have lace on front from ear to ear and on rear (neckline). Thus the construction of the wig allows it to be adjustable to fit a wider range of customers. The lace is positioned on the hair line and the neck line. It can be worn in a high pony tail but there is no lace on the crown. An example of those wigs are Full Lace Ganga wig, Full Lace Gauri wig and other by Janet Collection.
Half lace wigs on the other side offer frontal lace extending further into the crown. These wigs cannot be but in a high ponytail but offer better parting on the front.
