Weft
These are long tracks, or curtains, upon which the hair is already attached. This has been made by hand of by machine previously. Hand made wefts are custom made to suit your head and your hair. The hair is then attached using one row (or track) at a time. As with strand by strand extensions, care should be taken to avoid pain. Some methods of weft extension application, such as braiding or weaving can cause a lot of tension in the head, but attention to be made to keeping them comfortable.
