Bumble and bumble Sunday Shampoo
Lots of my recommendations seem to mention smell, and this one will too -- I love the freshness of this shampoo. There are probably cheaper product-cleansing shampoos out there, but it doesn't matter. I love this stuff. While I don't always use it on Sundays, I do use it at least once a week as my curly, frizzy mop needs so much product to keep it tame that I need to clean the gunk out fairly regularly. The Boyfriend also uses this when he stays over. It's blue, so he doesn't mind using it as much.
