This is my experience also. I don't buy it regularly, due to the cost, but I've not found anything in the shaving soap makers world that compares.Based on a dozen false starts with bar shampoo, I'm totally convinced: the highest-quality (great hair results), best value-for-money (number of shampoos from one bar) comes from LUSH. Kinda girly - they do always have a couple non-fruity varieties targeted at men, though frustratingly they always seem to limited editions and therefore if you like some variety you have to reorder fast or it probably won't be available.
But still, I don't think I'll experiment with any more brands, none of them have ever come close to whatever LUSH happens to be selling men.
