I have a bottle that I've had for quite awhile (maybe 6-8 months) and it's almost empty so I bought a new bottle a few weeks ago. I just checked the ingredients and both bottles are identical. I guess the difference is all in your head!

I like the idea of using it to dilute a heavier conditioner...I may have to try that!
