I use sally's version of k-pak for a protein treatment once a month (if your hair handles protein well, you should try it).
For a clarifying low poo occasionally (if I feel like I have some kind of build up or before a protein treatment), I use ION Color Defense Clarifying Shampoo (my hair isn't colored, but that doesn't matter, it's sulfate free and gentle)
I use Biotera Leave-In Conditioner
I use Beyond the Zone Noodle Head Tame your Curls Mousse
I am experimenting right now with biotera curl creme and biotera styling gel

Sally's is awesome!
