You do not need shampoo at all - use as
hot water as you can comfortably stand, and then rise with some good for hair strong herbal infusion. I started doing that a few months ago, and my hair looks better than with shampoo, and bonus is, that my scalp doesn't itch for several days after washing my hair. First time your hair might be a bit oilier, but it adjusts very quickly. It is actually much healthier for our hair not to try to make up with oils, because of our harsh treatment. Soap is harsh, even if it is natural. Also do not soap your whole body daily since it takes 48 hours for us to absorb vit D our skin makes. I soap just parts that sweat a lot. Bar soap is really easy to make, I make ours once year. It is possible to make liquid soap (your own dr. bronners!), but it takes a bit more playing around. If you have lots of space, maybe you could experiment with soapy plants such as soapwort?
Toothpaste is also not needed since from my
experience it never cleans teeth properly -store bought or natural clay one (I used to make one from bentonite clay, water, and peppermint essential oil). Use teeth cleaning sticks. I use licorice
root ones I bought, but you can plant your own or use willow branches (nicest texture) or other nontoxic tree branch, that is about a pencil diameter. Just soak the end for a few minutes, peel off the bark a bit, and chew to soften it, then brush gently. You will be surprised, how clean your teeth will be. I also do oil pulling once a day -coconut oil, a bit of baking soda and a bit of turmeric powder. You could use any oil -grow sunflower seeds and squeeze them out?
My laundry soap is made from washing soda, liquid soap, baking soda and water. You can make your own washing soda from baking soda baked in 400 degrees over for about an hour. You will see, when it will become washing soda, texture will change - it will form balls easily instead of being soft powder.
You didn't ask for these, but zinc oxide powder makes perfect sunlotion, diaper rash, or deodorant, if added to coconut oil or jojoba oil.
Milk of magnesia by itself is very effective deodorant as well.
I would include herbal medicines as your staples as well -make sure you have ready made stuff from pain, inflammation, herbal antivirals and antibacterials, some clay to pull out splinters, infections, insect sting or animal bite poison or bacteria, also activated charcoal powder for food poisoning, diahrrhea, etc.
