If I knew the cost of this little bottle, the “wallet” would have stayed in my pants. This little one exceeded all “expectations”. Yes, I guess it’s great shampoo, but definitely not worth $800. The truth is, it’s not the product or the container that matters, but where it decided to go that brought up its price tag. A little trip, not on my hair but down the sink, cost me enough to say size really matters, and sometimes the best things come in large packages. Oh well, you live, and you drain.
