The listing, Blond Hair extensions has ended.
These are 100% human hair that was applied professionally with crimp beads. The lengths vary but none less than about 6", they were applied to my whole head but were in for less than a full day and I just could not stand them so I had her remove them. They come with a jar of blond crimps, and most of the pieces have the original crimps on them still - I don't know if they are able to be reused or not as I am not a stylist or anything. These are quality extensions that cost over $500, and if you were thinking of a cheaper way you could probably have a friend apply them without too much trouble:) I am sure there is a website or video on the web that could show you how and what you would need...
