Full lace wigs are 100% hand-tied with a cap, and a thin lace sewn on top of the cap. Individual hairs are then sewn into the thin lace. Full lace wigs will have lace all around the unit, and require the lace to be cut all around the unit. You will be cutting a hairline around your entire head. By doing so, once done you can wear your hair anyway you like, ponytails, up-dos etc.
The 150% density full lace wig has a lot of flexibility for many styles.
