For those who want to change their looks dramatically, hair extensions offer the perfect combination of versatility and length. Although sew-ins are a very popular method of attaching extensions, glued hair is another approach that many people have been experimenting with. Instead of having to contend with sewn closures or the temporariness of clip-ins, glue-ins allow individuals to apply extensions on a strand-by-strand level. It is not surprising that people have been turning to this option more often as of late.
