Diet Suds

Standing in my shower the other day I noticed that my shampoo features "Lite Nutritive Fruit Micro-Oils." Now all of this seems like marketing mumbo jumbo, but mostly I am wondering about the 'lite' part. Is this diet shampoo? They used the common diet misspelling indicating low calories or low fat or whatever, and I can't think of another reason that might be listed on the bottle. Do people put their hair on a diet? Next thing, my conditioner will probably have 'no trans fats' listed on the label. And you know what comes after that: a lawsuit and the warning 'not for consumption.'
