The smell - I dont know, I guess it smells like their no poo. as for how it goes on, it is different consistancy than a mousse; mousses are like shaving cream, and the foam is more like Aveda's Phomollient. I use 1 1 /2 pumps, top/back and on each side. I really do like it.

I know most curly hair needs support from products, except those lucky enough to use conditioner only styling, but I dont think curls should be glued in place!
