17. Sorry, Not Buying The No Shampoo Thing

I know quite a lot about surface chemistry and how surfactants work. There is no substitute, in my mind, with something that hits critical micellar state and is still mild to the hair and skin.

Soap is a BAD replacement because it has almost zero hard water tolerance. (Think bathtub ring! That's the calcium replacement ions falling out of solution. Nearly completely insoluble in water so that stuff stays on the skin and hair too!)

Water isn't "wet enough" naturally to remove oily residues from the skin and hair.

On your tortilla thing: that does seem odd. I know parabens metabolize rather easily in the body, but it does seem silly for something in a sealed bag that then will be gone in less than a week to need a preservative.
