Full lace wigs are manufactured with a cap, and a thin lace sewn on the top of the cap. 100% human hairs are sewn into the thin lace. Best full lace wigs have lace all around the unit which should be cut when you wear them. You will be cutting a hairline around your entire head. By doing so, once done you can wear your hair anyway you like, free parting, ponytails and up-dos.
