I've always been inquisitive about this, what are tape-in extensions...but well, here's the answer (finally). If you ever see a hair expert with a glue gun, just know it's not for art and craft but for magic on the locks. We're referring to tape-in hair extensions. Yes, they are pre-taped and then taped or glued on either side of your real hair. These are attached using a heated tool that ensures the glue sticks. So much so, because of how firm the glue is, the process can take up to an hour - I mean, worth the wait right? While its firm hold can let you dance and spin, without the fear of the hair falling off, it also has its drawbacks. As your natural hair grows, these extensions can also fall lower and lower, looking unkempt. Also, the heat of the glue and the adhesive's texture can damage the protein of your hair and hence, hamper the quality.
