I quit using shampoo and store bought soap a year ago I bathe everyday with warm water and sand. I keep the sand in a five gallon bucket. I take my wash cloth and grab a chunk of sand and just scrub really good my hair and body. I had went a few months without seeing anybody when I started this regimine. And my mother who could always tell when I skipped a shower. Did nothing but compliment me for months on my hair quality and skin healthiness.I have been experimenting wiith adding crushed mint leaves and a little cinnamon to my sand and my wife loves my odor but I cant convince her to go all natural cleaning products she claims to many years of use and that her needs cant be met my way I do use orange goop to remove oil and grease when i work on mechanical things. I did notice at first I was greasy  feeling often but not anymore that lasted about six weeks.It used to seem like everytime I got out of the shower I had acne but not anymore but I should note I also quit shaving and using aftershave and most of my acne may have been shaving related
