help with hair extensions!?

Question

I'm trying to make & sell my own hair extensions,
one of my friends does it, here's her site:

http://ddextensions.bigcartel.com/

& I was kind of wondering how I could make hair extensions like that?
would I just take a synthetic braid & make it into an extension?
or would I actually have to buy human hair?
