FWIW, baby shampoo works fine for washing hair, body, dishes, and clothing (including in a washing machine). It is pretty convenient as an only soap to carry on tour. It probably even works fine for shaving as well, but since I don't shave on tour and just use plain water at home I am not the one to say.
Campsuds are OK for all of those purposes as well.
Personally I think that Dr. Bronners was inferior to both of the above choices.
Oh and one other thing... For saddle soreness Balmex or other zinc oxide based diaper creme worn overnight works like magic.
