How do y'all use Miss Jessie's?

I was browsing curl mart (in the event there's some sort of special for December...hint hint) and was wondering who uses miss Jessie's an how? I'm not sure it would be for me. I'm a 3A/3B and finally getting enough length to weigh down the curls. Does anyone with that type use it, and if so, how do you use it? I don't know the first thing about it. Kinda afraid since I think it's geared toward ethnic hair, and mine is just plain curly.
Hair type 3A. Jessicurl is becoming my HG!
