My two cents..
I have been experimenting with the small bottle of Curl Keeper. Long story short: I ordered the larger bottle because my curls are great. I use it with Biotera GLAZE - not the gel - and I get great bouncy, shiny curls. I am not CG. Another "bonus" is that you can "fix" your hair without it frizzing, you know, adjust the spots that are not quite right. I just give my hair a spritz of lavendar water, add a bit of the CK and its great. Also nice to have simplified my routine.
