Abstract: A hair extension apparatus and a method for attaching multiple interchangeable hair extensions to a user's head and hair. The hair extension apparatus has a hair extension base to which each of the interchangeable hair extensions is attached. Each of the interchangeable hair extensions is selectively engaged with the hair extension base, allowing extensions to be readily attached or detached. The hair extension base is divided into multiple mounting sections, allowing for the layering of the interchangeable hair extensions. A plurality of fastening clips secures the hair extension base to a user's natural hair, wherein each of the plurality of fastening clips can be configured between an open position and a closed position; a securing cord may also be used to further secure the hair extension base to the user's head.

Abstract: Peptidomimetic azatides and combinatorial oligoazitide libraries are produced by means of a stepwise synthesis. Combinatorial library construction of this new biomimetic polymer provides a means to fabricate global peptidomimetic libraries.
