Styling product for curly hair?

I have naturally curly hair and am looking for a product that help with frizz and keep my curls looking natural. I don't like blow drying my hair, so I let it dry naturally and then I braid it before I go to bed. When I wake up, I untie my hair and my curls are really soft and look great, but I'd like to find a product that I can just put on my hair in the morning, when it's dry, so my curls will stay. Any suggestions?
