I heard of this a few weeks ago, I think it is a gimmick as I imagine they they cannot possibly do this, hair absorbs fumes and pollution, I have worked in bars years ago when I was a student and my hair would reek of cigarette smoke and alcohol-I smelt like a chain smoking alcholic! :lol: Who would want a whiff of that- it would stop the stalkers and unwanted attention though! People will buy and beleive anything.
