Hey, so i have about 5inches of hair, and my hair is reallllly strong, and wawy. Not the most wawy, but not straight for sure. I have a slickback hair, and i want it to be look really natural, so if i bend down, or run or something like that i want it to hang down. And i see that other people with shorter but straighter hair can do that. But for me, it’s never hang down, it’s just always rises to the  clouds. So my question is, how many inches of hair i need to hang down a really strong, somewhat wawy hair? Sorry if my text is confusing, my main language is not english.
