I bought these extensions in the 8 inch size, color #33. I absolutely love them. They are human, so they act just like human hair. They can be flat-ironed, curled, etc. and cleaning and brushing are so simple. These are perfect for anyone who doesn't want to pay hundreds of dollars for extensions. You do have to pay for clips but I bought Snap Clips (also from Sally's, in stores they are right next to each other). The clips work very well and don't get pulled out unless you are purposely trying to, but that's a different review. All in all it's like magic growth for your hair because they come in multiple colors, but on the website this extension doesn't have blonde.
