Static Schmatic for Hair (Set of 2)

I purchased this a year ago for myself and my daughters. The first few times I used it I found that it didn't help much with the static and that it was as if I were just spraying water on my hair. So I put it away and started using The Honest Company's Conditioning Detangler instead. Today, I ran out of it while doing my daughter's hair and decided to get out the Static Schmatic again. I don't know if there is an expiration date on this product or if the oils in it get rancid after just one year because I sprayed it on my daughter's hair and it smelled like vomit. She even said to me, "Mommy, what is that stinky smell?" Needless, to say I was pretty annoyed because I had to clean the smell out of her hair and throw two bottles away.

Outstanding product for those who hate static and hate "refreshing scents" even more. No scent, no static. Perfect product.
