Just a thought.
Ombre hair is the most popular thing for celebs these days.
I'm pretty sure some celebrity saw a woman walk into the salon
(a woman who has NOT had her highlights redone in a year), and said "THATS HOTT!"
thus making ombre hair popular
but all us poor folks know its just you couldn't get your hightlights redone until you paid off some bills.
Still I really like ombre hair. I'm just saying there is a story to it :)
