Query: Do NOT buy!!!

Please do not waste your money on Paul Mitchell if it's not from a salon. I bought this and realized quickly it is old! VERY OLD!!! It smells so bad. I have used this conditioner in the past (bought from a salon) and it smelled great! This stuff smells awful. It still works well, which is why I gave it 2 stars, but it does smell. I then thought to look at the bottom of the bottle. I believe it expired in September 2011. I bought it in October 2012. Need I say more?
