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?
