Review (4/5): Good enough
Don't have other extension experience to compare it to, but I feel that the hair was a little dry and brittle. Heavily processed for sure, you could smell it. However, it matched my hair nicely and looked real and it was easy to work with.
You should note that these are HALF GRAM (1/2g) pieces!
I have a sensitive scalp so I took my extensions out within several days. It's uncomfortable to sleep in them and they always felt like they were pulling on my skin one way or another. You can't run your fingers through your hair or scratch any itches very well without pulling on your hair. I was developing a headache from the constant pulling, but like I said, I have an extremely sensitive scalp.
Do your homework and weigh your options. If you have short hair, best to wait for it to grow out closer to the shoulders for these kinds of extensions to look good.
