I've used Dr. Bronner's for just every use that I can think of. (from body wash to laundry soap and everything in between). My only problem is I can't find a decent shampoo that will get rid of dandruff. Dr. Bronner's just makes my hair feel greasier and not washing it on a regular basis is just plain nasty. What's a hiker to do? What do the folks use to wash their hair at home or on the trail?
