Query: Air Freshener for your Hair

For those of you who like to add an extra step of grooming in the morning with no measurable results, look no further. This is the product! I have been a faithful B & B user for over ten years (and have converted others to the seaweed shampoo and conditioner!) and this stuff is a waste of money. It smells good (really good) but then it evaporates leaving my hair no more manageable, shiny or conditioned than before. It's like a handshake for your hair. I feel cheated for having spent the money. Learn from my mistake!
