Myrna, I have exactly the same experience as you: if I use just the foam I have great shiny curls that don't last - so that is why I think I need to use a gel over it.

BTW, the best curl creme I have tried is Curl Junkie Coffee Cocoa Curl-creme Lite (CCCL) which is a favorite of many on this site.

I never thought of curl creme and foam and I wonder whether that would give sufficient hold. Might be a great combo in different weather when the dewpoint is higher and there isn't much wind. More experimenting is in my future - I can see that.
2/c and some 3A.
Protein sensitive but can use occasionally
Highly porous. Color over grey.
Best 1st day method: Super Soaker
Stylers: Mix Curls in a Bottle into everything for shine. Terrible pj
Sometimes try roller sets - classic glamor but I prefer my curls.
Every day is a gift
