Not just a natural handmade shampoo bar
The reason I call these natural handmade shampoo bars is because that's really what they are. Now I know you're having difficulty getting your head round the idea that shampoo would not flow from a bottle onto your hands to be distributed around your hair. I get your confusion. But you really should suspend your judgment on how a shampoo should be, leave your prejudices behind you temporarily and try it.
All you have to do is rub it on your hair at which stage it will lather up into a beautiful creamy lather, let your fingers massage it around the hair. Then leaving it for a minute or two for it to do its magic rinse off and listen to the squeaky noise coming from your very very clean hair.
I like to brush my hair straight away and then, because I have long hair, put it up in a bun for an hour or two and then let it out. With me, I don't have to use conditioner, the soap does that for me. Maybe you need to always put conditioner in your hair. If so, then do it as usual.
This shampoo bar can also be used as a soap (your visitors will love you) , a very luxuriant soap, Likewise it can be used for shaving. In fact, we have one shampoo bar with cedarwood and bergamot especially for men.
And if you really can't get past the "bar" element of these, I will be working on a natural liquid soap; it's in the investigative stage. Just Watch this Space
