Conditioner Bars work very differently from soap bars, most importantly they don't lather and clean, they are creamy and moisturising.
The feedback has been amazing on these bars, they last a very long time, testers which were a quarter of a bar have barely changed in size for a lot of people. Of course the time they last will vary with individual usage, hair length, how often etc.
After washing hair you stroke the conditioner bar over the hair until it feels silky and conditioned. Hair should feel similar to the feel of regular conditioner on hair. Personally I only use the bar from the ears down and hold the bar and use a combing motion with my fingers to distribute through hair, also detangling at the same time.
