I tried a shampoo bar today for the first time, a QCS Peppermint Eucalyptus. "Loaded" my hair with the bar in my right hand rubbing it all over my head and working it in with my left hand, after about 15 seconds of applying the bar I had a HUGE amount of lather, a fist full in my left hand! I rubbed it in vigorously (watch the eyes, OUCH!) and left the shampoo in my hair while I washed my body. Rinsed it out at the end of my shower and WOW - hair is soft and clean and manageable without conditioner. So far, I'm a believer!
