My MIL gave me her birchbox sample because I travel a lot. So, I took this on a trip and used it. It was awful. I didn't lather, or clean my hair. I actually switched to using the hotel shampoo because this was the worst.
Don't buy it if you have color treated hair, long hair, or dry hair. You will use a TON of it just to get it clean.
The smell is bad too.
