This looks great - how long does it last?

I love it!!! I bought more and I'm going to give it another try this weekend. I got really great results the first two times and I want to try your method of using more curlformers.

Let me be the first to say... you hair turned out. lovely!
What products did you use before and after putting in the curlformers i.e. conditioners, setting lotions, leave-ins etc.?
Also, how long did the set last and how do you maintain the curls?
