ombre hair

so i've been bored with my hair for a while. i have my natural light brown stick straight hair and i get natural highlights from the sun in the summer.. i like the undone and natural look of grown-out highlights. actually, now that i look back at old photos of me from 5 years ago, my hair looked similar to this after a summer spent in the sun..hm!!! vacation or hair salon? :) (3rd photo is courtesy of stockholm streetstyle).
