I have found an alternative to using shampoo. It is an Organic Mud Cleanser from Mahogany Naturals. Made of all natural ingredients. The main ingredients that helps in removing dirt are Bentonite clay and Rhassoul clay.
Bentonite clay is known to remove toxins and dirt from the scalp and hair without stripping your hair of all the good moisture and Rhassoul clay is a moisturising treatment it leaves the hair really soft and manageable. you did not need to apply a conditioner after doing the wash. It is good stuff really.
The link below shows my application method and review after rinsing off the mud. check it out
I hope you like it if you have any questions ask me anytime x
