Hair extension glue is DEFINITELY not the same as super glue. When you apply hair extension glue onto a weft, the weft and glue are applied directly to the hair. If you were to do the same thing with super glue, your hair would get ripped out. I'm not sure of the chemical composition of hair extension glue, but hair extension glue is designed to adhere to hair and to come out after a while, ordinary super glue is designed to keep things stuck together. Good luck!
