I am a long-time lover of Hair Extensions. Back in the day they applied these from individual strands (fusion not weaves) by using Keratin glue they melted in a hot pot. The process takes FOREVER. I know alot of companies have come out with pre-tipped fusion hair. I have yet to use these since I hate to switch from whats working for me. But more and more stylists are switching to these since its easier to put in. Anyone use these and had luck. I want to make sure there is enough glue so that the hair stays in.
