I haven't yet tried the activator but I've been using the Hawaiian Silky 14-1 (it's sort of a watery gel-cream in a trigger spray bottle) for years. It really activates curls, moisturizers, and soothes my scalp. There's just nothing else like it around - and it's cheap!
These days I'm 3B & can even get to 3C depending on humidity, but I think this product would be great for tighter curls as well!
I think Hawaiian Silky is one of those "best kept secrets of people with great hair" lines.
