I for one am not crazy about the scent. However, they claim that as long as you can smell the scent of MS that it is repelling insects. I've been using it for three weeks and am getting used to the smell, but still prefer her old "vanilla butter" dessert sweetness. It has cut down on her bath time. There is no need for conditioner and waiting for it to "do it's thing". With MS it seems like their fur needs conditioner, but after drying and brushing it is as soft and smooth as ever. That alone has kept me with MS.
As far as itching, no improvement...
