Query: BB disappoints

Based on all of the positive reviews here, I thought this product would be great for my naturally wavy hair. Unfortunately, it did absolutely nothing. No hold. No curl boost. No shine. No nothing. I really wanted to like this product, trying several different ways of styling with it, from letting it air dry to finger curling and diffusing. But I got nothing but a frizzy, dull, definitionless mop of hair from this product. It probably works well for people with super curly hair, but if your hair is wavy, go ahead and pass on this overpriced bottle of blah. I'll be returning the product to BB.
