Bonds and tape’s are a glue method the Keratinbond tips get heated up and then rolled around sections of the natural hair 

The tape extensions are sandwiched either side of sections of natural hair and pressed down 

Single Strand hair extensions get attached to the natural hair using small beads and need maintenance every 4-8 weeks where the beads are re-opened or fresh beads attached and the extensions are fitted back up to the top of the hair strand
