Greasy hair and an unwanted texture?

I'm a 16 year old girl. My hair is shoulder-length and the texture is wavy some days and curly others. I shower everyday. I shampoo my whole head every other day, I condition just the ends of my hair every day. I shower usually and hour or two before bed. The next day my hair feels greasy, it isn't soft and the texture is terrible. It isn't curly yet it isn't wavy and it is difficult to style it since it won't stay. Why is this happening and what should I do? I use Lo'real reconstructing shampoo and Herbal Essence tousle me softly conditioner. I like to wear my hair curly and my bangs either blown out or straight. I let my hair air dry. please help
