Alec Baldwin Medium Hair Style

hi, i was wondering if anybody could tell me how i can make my natural wavy hair to straight hair without using but shampoo, conditioner, and a hair brush. there were days my hair would sometimes go straight when i brushed my hair in a certain way, but every time i try to remember how i did it, it never comes out like before. and the days it would come out straight, which were few, or that it would come out alittle wavy and straight, were the times i wish i could've remembered how to do it again. does any know how to make wavy hair into straight hair without using anything but shampoo, conditioner, and a hair brush? and my hair is wavy but not to the extremes, just enough wavy.
