hair frizz

Hi,
My hair is typically Indian black. I am a male & have long hair. Whenever I wash my hair it appears little frizzy. After a couple of days it is better. I dont want a straight hair but i have seen some hair that are kind of smooth still retaining their natural curve (not actually straightened) but they have a moisturized texture and also even after strong wind they tend to come to their place and they appear as if it is not disturbed. I don't know how to explain. As far as my hair, If it is subjected to moderate wind, it is disturbed and the hair will rise a bit and stay away from the head. I just don't understand the secret what makes some people hair in really a good texture. mine is not too curly and it has some natural waves, also it is thick. The texture is comparable to the fibers of the tender coconut. It is not that weird but yes it certainly needs some thing to hold it. but i would certainly like to better my hair's texture I don't prefer straightening either. like to have a naturally flowing hair with a smooth and moisturized appearance not a straightened one....

Please give me some suggestion.
