Eli5: What’s the difference between soap, body wash, shampoo and foam bath?

194 views

There are literally isles of products at the local drug store and I wonder what the difference is between different types of bodily cleaning/foaming products? For example, why can’t we just use just shampoo or just body wash on our whole bodies? Why are there so many different products?

Soap is generic, yoi could basicly wash everything with soap, soap specific for body is body wash and for hair shampoo. Foam bath is nothing you apply directly to wash yourself it enhances you bathing with fragrance and foam.

There are some soaps you can use all over your hair and body. But they are very basic and don’t target specific concerns.

Different shampoo help with the many different hair types and scalp concerns. You don’t want to use general soap on your hair because overtime it can dry out your hair and scalp. It might wash away too much of the natural oils.

The skin on the body has different concerns too. Some may need extra moisturizing soap, others may want more exfoliating soap.

If you check out ingredients you’ll see that a lot of it is mostly the same stuff. Capitalism loves to take the same thing, and try to sell it to you as something different, hence the endless aisles of thousands of products

Soap is fatty acids reacted with a base to produce glycerin and long chain molecules that attach to both water an oil. The chains strip oils and the glycerin moisturizes. The problem is that they remove this glycerin in most soaps and resell it for industrial use.

The rest is usually detergents and foaming agents, which are synthetic compounds that are very good at stripping all oils off of a surface. This is why you need to use conditioner after shampoo.
