Good idea, doesn't work well

After hearing a lot of positive reviews about shampoo bars, I bought one on sale. It smelled great in the box, just like the other products by this brand. However, seems to leave a residue on my hair that makes it gritty and heavy. Also does not seem to do a good job of cleaning my hair. The smell in the shower is not as good as when it is in the box. I do smell generic soap smells. Happy to keep using my opened box, but not buy more, even if on sale.
