Another popular alternative to acrylic or gel preparations are fiberglass or silk wraps. They are done by cutting pieces of actual fiberglass or silk fabric to fit on the surface of the nail or tip and then it is sealed down with a resin or glue. These are an alternative for those who are allergic to chemicals used in the acrylic or gel process. Other materials can be used, as well as combinations of them. There are also temporary, cheaper flexible tips that can be quickly glued at home without help from a professional.
