I actually got a whole Tigi Bed Head Dumb Blonde set, with shampoo, conditioner and leave in conditioner, but I'll tell you more about the other two products in separate posts, since some of the products actually turned out to be better than others.
Another great thing about the Tigi Bed Head Dumb Blonde shampoo is that you need very little of it to wash your hair completely. I've never used a shampoo that seems to be so efficient! So I think a bottle will last for a really, really long time. (I am nowhere near using up mine yet)
My hair feels very clean after I wash it with this, but I can't say my hair got softer, less dry or better in any way after using this, which is basically what I am looking for right now. So this is not the perfect shampoo for me for that reason, but I really like it other than that.
