so basically, due to the extreme lack of hair products in the uk,i found some ecostyler online for cheap, which i know is used a lot in the curl world...anyway i am not sure which one to get. ive eliminated the pink one and the protein one, but i am unsure whether to get the krsytal one, the argan oil one, or the olive oil one. i dont want my hair to be crunchy, but i want good hold and shine,and i prefer looser curls. which one is for me?please reply soon as i need to order it tonight!

ps. my hair is low porosity, and ranges from 2a (underneath) to 3a.
