But, I have found one issue with this cleansing regime: it does not get sand out of your hair. I went to the beach on the Kona side last weekend and it was so windy that it pretty much imbedded the sand into my scalp. Normal shampoo lathers up and grabs all the tiniest little particles. Since baking soda doesn't lather, it didn't grab all the teeny particles so my scalp was still quiet sandy after my shower. I took a fine-tooth comb over my scalp and worked out most of the sand the next day before I went to class, so it wasn't the end of the world. I suggest that avid beach bums might want to use a natural shampoo that lather instead of the baking soda/vinegar regime if they don't like waking up with a sandy pillow.
