I can't point to one shampoo and say that it is the very best. I am using MinkSheen right now and love it -- it is so convenient and easy to use, you don't have to use a conditioner so that cuts out an extra step and unlike many poeple who review MinkSheen I LOVE LOVE LOVE the scent.
I also love Cranberry Fields from Kathryn at
www.BeyondSpoiled.com and Coat Handlers.
