Update! (Because you're all dying to know...)
For the most part, this worked. As you can see in the terribly unflattering before photo, my hair was a frizzy mess (i had been in braids and took those out), thus it's still a bit frizzy today. There are a few pieces down the center where it doesn't look like it took at all, and a pretty bad kink where the pony tail started. I'm going to try again with fresh hair this time and see what happens then.
Oh and because I had so many questions, here's the original post (videos below), that inspired me. This gal got herself some purdy hair.
