stop washing my hair

I havn’t been washing my hair every day because i honestly havn’t had the time! But after hearing in a magazine about stars not washing their hair for months on end to get beautiful, soft, shiny, hair…i’ve decided i’d give it a try! I’ve been using a dry shampoo or baby powder to absorb some of the greasy looking roots…and can anyone weigh in on the end results of just washing your hair with cold water, washing with warm water, and not letting it touch water at all? So far it’s been three days! :) I’ll see how my first week goes here. :)
