How to make my own spa products?


I would like to make my own:
Shampoo/Conditioner
Body Wash
Shaving Gel
Body Scrub
Bath Salts
Lotion
and whatever else there is to make.



I would like the products to be edible. I'm trying to protect my body,

Why am I asking this? I'm tired of the chemicals in skin care/spa products.

If you only know how to make one thing, that is fine. But if you know how to make more then one please tell me. :) Thank you for your help.
Why? Because it's easier to go buy it?
