Pros: adds great length and volume, easy to put in and take out, styles very easily can wash as often as needed, comes in many different colors and can be dyed
Cons: need to be cut if adding to very layered hair, hair needs to be medium length to look natural, too shiny at first but goes away after washing

"These extensions are the best ones out there. I have gone through 3 types of extensions and these ones last the longest. (I wear my extensions almost every day). The clips are strongly sewn in and the hair is so easy to style. I have put mine through the wringer with spiral curling, updos, dyes, and general styling. I highly recommend these to anyone who has shoulder length hair and wants to add some inches or volume. They are fantastic. I don't recommend these to shorter haired people though because they start to look a little fake if your real hair doesn't cover them enough to look natural."
