Where can I get hair retipped?

just find some really good keratin glue sticks and an old straightener you dont care if it get glue on it. I have a melting pot personally and i just dip and roll with my fingers but you may not have one of those. So rub the stick on the flat iron after its hot put the hair tip where you want the glue to stick to it and close the straightner make sure it gets on the hair then just roll it back to the stick shape with your fingers. the only thing you can really do to mess them up is make the stick part to long but just cut it with scissors... hope it helped. 

I need some of my extensions retipped but dont know of any place that I can send them in to. Is there such places that will do them for you. I dont know how to retip and dont want to ruin the extensions by tryin to do them myself. Can any help me out or refer any place?
