I've been searching for a shampoo bar and have tried several.  All of the previous brands leave a waxy/oily residue which is very difficult to rinse out and makes my fine hair look/feel matted & unhealthy.  The Rustic Charm Goat Milk Bar is the first one which rinses fairly clean leaving my hair more natural looking and it doesn't make my scalp itchy (although I need to rinse a little longer than with regular shampoo). The search may continue but so far this shampoo bar is the winner.
