Keratin hair extensions are normal hair extenders which add volume and length to the human hair. The extensions look like a small wisp of a human hair but with a keratin based dried glue at one end. The hair extensions can be curled, dyed, straightened, styled with heat and everything that you would do with a normal human hair. The extensions are placed in rows and are strategically covered with another piece of hair even when you wear a ponytail.
