Is there really any difference between the seemingly infinite amounts of brands of shampoo, conditioner, soap, toothpaste, etc., or do they basically all do the same thing?

When you break the ingredients used down to their actual sources the answer is a lot more clear. No, there isn't really much difference, chemically speaking, between Crest and Colgate or Tresemme and Pantene.

 While the source ingredient and overall content of the product is very similar ,the 2% that they change can have a very large effect on how it works or tastes. 

An easy analogue for this is cheese. Nearly all cheese comes from the same source, milk. If you break down the chemical composition it is largely the same from any kind of cheese... but does it taste different? Yes, very much so.
