I shower at night go to bed then go to school But after go to sleep that day after school my hair gets greasy at the top of my head How can I prevent that?

To prevent hair from becoming greasy during sleep, wash the hair frequently throughout the week. Use hair conditioners at the tips of the hair and rinse your hair using warm rather with cold water at the cuticle. Avoid using a lot of hair grease and limit the amount of times a day the hair is brushed to prevent oil from the glands from releasing on the hair strands.
