Most use FOTE AVG - it's pretty readily available. I've never been able to find the Theraneem, but I'd like to try it.
AVG is more for curl enhancement and maybe a little additional light moisture than for hold - most find it gives very little actual hold on its own.
I used to always use a generous amount of it on my very wet hair before I applied any other product for frizz control and curl enhancement. I'm not needing it much nowadays with the products I'm using.
I do usually still apply it to my pineapple the first night after washing my hair to reinforce the curls - helps me get day 3-4 hair, sometimes longer.
