Today we're talking about human hair weaves versus synthetic hair weaves.
The obvious is, with a synthetic hair weave, you can't use your flat iron. You can't use your curlers. Once you put it in, it is what it is out of the box. That's it.
Most people don't wash it because they don't want to change the curl or the sheen that's on synthetic hair. That is a very bad thing, because you want to be able to wash your hair, so you shouldn't be walking around without washing your hair.
Indian hair, or the human hair that most people use, the difference between that and the synthetic is that you can use a straightening comb, you can use a flat iron, you can use curlers. It's way more versatile. You can wash your hair, you can condition your hair, you can do anything you want.
You can do anything you want with the Indian or the human hair weave that you would do with your natural hair; but you can't do the same thing with a synthetic hair weave because that hair is just how it comes out of the package.
