I'm pretty new too (which is why I caution everyone that they might want a second opinion on any of my suggestions lol), but I am still searching for my HG curl enhancer. I had amazing results with KCCC the first time I used it (before I started using lots of protein) - awesome clumps and my hair was SO soft. Unfortunately I haven't been able to duplicate those results, but I can't honestly say it's ever given me "bad" results - just not as great as the first time. The KCCC is all moisture, there's no protein in it at all, so I use Curl Fix and Ecostyler I also really love AG Recoil. The protein is pretty far down on the list, but it works great no matter what leave-in I use (even if I don't use one). Unlike KCCC and CCCC though, the Recoil breaks up clumps and gives me lots of smaller spirals all over. I usually use a protein gel over this too.
But my favorite "curl enhancer" is the pixie-curl method:
The No-Frizz Pixie Curl Method
I use it with pretty much everything I put in my hair. It took me a little while to get used to my hair looking worse at first - my curls looked really squished and tangled - but once I finish drying, flip back over, and shake my head a few times my hair looks awesome. My waves are 3a-3b curls and they stay that way until I get home - I love it! I never got so many compliments on my hair as when I started using pixie-curl. One of the girls I work with even told me that I had "perfect ringlets" (eee!
)
One last suggestion I can offer is to find someone (or a few people!) on the boards who have the same hair characteristics as you. Check out their siggies to see what products and/or techniques they use. This can help guide you on what might work well for your hair type.
