You ladies are awesome! Thanks for taking the time to answer my silly little question
In a nutshell, I experimented like crazy when I first joined this site and have learned that protein, mousse, coconut oil, anything Curl Junkie, and curl creams are not my friends

Everything else seems to be fair game, though.
I had been using KCCC religiously for 3 years, but it recently started to seem like it wasn't doing what it used to do. The Bioterra is pretty good. 90% of my hair looks quite lovely with the combination of products I'm using, it's just the top layer of my hair that has the problem. Actually, no matter what I've used, it is has always looked problematic. Which has lead me to always finish my hair with a hard hold gel -- it's needed just for that section alone.
I guess my problem is that that layer of hair is just much coarser (not really drier), and less curly than the rest of my hair so it's not reacting the same way to these products.
I tried adding another thin layer of the Renpure as a leave-in just for the canopy and skip curling (is that what it's called???) the top, and it looked better, but not good.
Do you have any recommendations for other jellies and more moisturizing conditioners I could try? Although, I have to admit, I'm loving the Renpure right now (was using Elucence and thought it was meh).
ETA: I used to love using the original Shea Moisture leave-in conditioner, back when it was referred to as SheaM on here. That did wonders for my hair. I can't find it locally, and online places want to charge more for shipping me two bottles than for what they actually cost. Is this Shea Moisture the same line as the one that is now sold at Target and elsewhere? I tried and disliked the stuff from Target.
