I also have very thin, fine hair. Mine is 2a-2b. It was normal porosity but might not be anymore since I got highlights. I like the jessicurl products because they have mag sulfate and I like spiral solutions (I heard they are made for fine hair) but other than that I can't give great advice because I have been inconsistent on my CG journey :/. Hopefully I can get better at my hair will transform like jkrussel. I also like homemade FSG which is basically what the jessicurl products are. I recently started using the volumax gel and like that too. My best waves happen when I apply products to soaking wet hair and then once it is all dried and I scrunch out the crunch I apply a little more gel to get more definition. But I never have time for all of that
