I got this in the set with the conditioner, bath soak and body wash in 75ml. It smells very nice and I only used a tiny amount. I noticed it was very thick and concentrated, so should last a while. It cleaned well, foamed up without effort. The only downside: don't expect much moisture, my hair felt dried out. The packaging is amazing, the best I've seen. I want to get it in the large bottle so that I can transfer other shampoos in! But after that repurchase, probably won't again.
I read the ingredients for the shampoo and body wash because they were very similar and they're nearly the same, so just buy the shampoo for multi use :)
