These hair extensions, which are usually made with real human hair, are arranged in rows into your hair so that you can move your hair about without giving it off. You can even have your hair up in a ponytail and the extensions won’t show.

The attachment of these extensions requires a heating agent, which is the keratin bond that’s used to attach the extensions to the hair.
