JessNP, I have crazy curly hair that frizzes easily. If you're a fellow curly girl, you won't be surprised that I have a few items I rotate in and out. One that I've tried recently is Alba Botanica Style Gel (Fragrance Free) in Strong Hold. I only have to use a dollop, along with a leave-in conditioner (I've been using Alba Botanica Fragrance Free Leave-In), and my hair stays relatively frizz-free. But then, I prefer a non-crunchy look. You know? Another good gel is Aubrey Organics Hair Design Gel B-5 All Natural... I have heard of gals using just a bit of aloe vera juice... but my hair needs A LOT of hold to control the frizz.
I think the overall key is to keep hair/scalp really conditioned... one good conditioner is Desert Essence Organics Conditioner in Coconut. Super moisturizing, but again- free of parabens, sodium lauryl/laureth sulfate, artificial color, etc.
Hope any of this helped! I know it's hard to find a product that works for your specific hair. What works for one curly won't necessarily work for another.
