Coconut oil!

I started doing Curly Girl about New Years--I had done it for a few months about 4 years ago also. Anyway, I've just been using Suave Eternal Sunshine as a co-wash, conditioner, and leave-in, and Suave gel (the pink one) and that's all. I live in Texas and things are starting to get frizzy here, so I've been thinking about trying to use some type of product when I scrunch out the crunch. Today I tried a tiny bit of coconut oil and it was dramatic! My avatar is my hair after a full day and walking for an hour in the humidity. This is completely blowing my mind! All these products add up to a total of less than $10! Can this really be all there is to it?
