I don't really have any recommendations for you, but it is not silly at all! I was going to try Yes to Cucumbers until I smelled it, and it smelled like a salad! Now however, it doesn't matter what my shampoo/condish smells like, I scented my FSG with coconut fragrance oil, and my hair will stay smelling like fresh coconuts for a couple of days at least, longer if I use my FSG again. I do use coconut scented shampoo and condish, but I really don't think that scent lasts as long.
