Conditioning Thought

My hair conditioner is running low again, but I still have plenty of shampoo left. It just seems that it takes more conditioner to do hydrate the hair than it takes shampoo to cleanse. Yet, both the bottles are exactly the same size. So, inevitably, I'm left scraping the insides of the conditioner bottle so that I can try to make it last until the shampoo is used up.

My thought is this: would some adventuresome hair cleansing company venture to make bottles of conditioner that contain maybe 1/4 more conditioner than the shampoo bottles contain shampoo? Maybe we need to conduct some studies to see if other people have this problem and if they do, exactly how much the conditioner should be enlarged.

Does anyone else suffer from this dilemma? Or do you have a better solution? I'm also wondering what your favorite shampoos and conditioners are? I always love trying new ones. My new favorite is John Frieda.
