How come my hair sticks out?

like for example.



lets say i come out of the shower (shampoo and conditioner) and like i towel dry it. and yea just let it go from there. but whenever later lets say i run or jog, my hair bounces and whenevr i stop it becomes a huge mess. it looks like a mushroom. i want my hair to stay on the back and to stick to the sides and not flop around. what could i do to make it better. i have thick hair. do i need to thinnen it out? wtf do i do lolHow come my hair sticks out?
no do not thin your hair only if you want that style because my hair is thinned out but im making my hair grow thicker.well when you come out of the shower brush your hair where you want it to stay and i know when you brush your hair it gets damaged when its wet. then you can put hairspray or something that makes your hair silky
