In a quest for ways of maximizing conditioning for my hair, I researched for months until I came across bentonite clay. Derived from volcanic ash, it is grayish brown in color, bentonite clay naturally conditions, naturally cleans, and naturally draws out grease and build-up that can be caused by many products or from sweat and dirt.
I have noticed a considerable difference in my hair since I began using it. My hair feels cleaner and more conditioned. The added bonus is that if you have any curls, it can really define them. And now I am completely in love with using it in hair care and beard care products. Since clay can be a pain to rinse out of hair, this is why I turned it into our first liquid shampoo and I have added to our creamy beard wash.
Tip: Be sure to rinse your hair until no more "cloudiness" comes from it when you squeeze water out, to ensure all of the clay has been removed.
