What I think many people lose sight of in these debates is the nature of your hair versus the nature of your scalp. Your scalp is like your skin (it
is your skin, as a matter of fact), and since each of these items has been used with varying degrees of success on other areas of skin on your body, people
can, theoretically, use them to successfully cleanse the scalp. Our hair, on the other hand, acts more like a fiber, as in like the fibers used to make our clothing. None of these items can be used effectively to cleanse our clothes and leave them soft and in good condition. Therefore, it stands to reason that neither clay, ACV or oil would be a completely effective cleanser for our hair
strands. As she said in the video, each might impart certain benefits to the hair as part of a more complete regimen, but using them as a primary cleaning agent would probably do more harm than good over time.
