Castile generally means any soap made with olive oil and in some cases coconut.  Natural castile does not contain foam boosters or chemical additives.  True, "natural" castile is free of artificial colors, fragrances, preservatives, animal products, their byproducts, and animal testing.  

Castile has traditionally been used throughout history as a cleansing agent.  After all, our great-great grandparents didn't use sulfates and bunch of other stuff most of us can hardly pronounce.  They often manufactured their own lye or plant based (castile) soaps.

What makes castile great is that it's ultra-mild.  Where I do not recommend it for use on baby's skin, it's terrific for teens and adults who have chemical sensitivity.  Unfortu
nately, there are companies that manufacturer concentrated castile and market these products as "catch-all"s with hundreds of uses.  Using such a product would be no different than using an over-the-counter sulfate.  If it can clean your grout, why are you using it on your hair?

Look for castiles that are specifically manufactured for use on hair.  You will find that these alkaline products will naturall soften even the hardest, driest hair.  Castiles should always be followed with a quality conditioner or herbal vinegar rinse to help restore your hair's natural PH.
