Review (5/5): Some people are insane.
I bought this without reading the reviews and now that I recently have I don't know what half of you are talking about.
These are probably the best extension tapes I've used by far.
Most others would be so bad, after a couple washes I'd have extensions already coming out, I first used this to install mine in October, and just now finally in December had to start taking them out because some of them were getting loose and coming out so I just took them out altogether.
Another reason you could be having problems with them, is because after you install your extensions you DO NOT wash your hair for 48 hours.
Wash your hair before putting them in, DO NOT use conditioner, and make sure your hair is completely dry.
Another thing that I do after watching many YouTube videos, is that I found sealing them with a straightener isn't as effective as sandwiching your hair, and then just using needle nose pliers, or whatever pliers you have available to really press both pieces together.
That's probably a big reason mine stay in so long. Because I have my friend use pliers and really press everywhere on the section she's working on before doing it again with another.
Try a different method of installing them before you give a bad review. It may not necessarily be the tape, but the installer.
