I get the lump stuff to start with the chimney starter - works like a charm. But cooking oil How smart is that!
And I tried not shampooing for about 2 weeks a few years ago after a hippie friend said something like, "it works for dogs... their body just figures out the oil level they need..." So I tried it. And I can see how it could totally work for some people, but I think my hair is too fine and thin for that. I have to wash it every day or I feel like an oil slick.
