I've had plenty of experience of these fabulous Narberth Soap Company products, but I've never come across a shampoo as a solid bar before. The one I tried was without perfume, and immediately I rubbed it on my hair it produced an incredibly rich and creamy lather. This was the best thing about it for me, the almost instant lather, and of course it's made of all natural products. And the next best thing was that for such a thick lather it washed out very easily, leaving a fresh, clean feeling with very little rinsing.
