How after thousands of years without shampoo and soap, we survived, and now we can’t even think in a life without it?

Question

I just don’t get it, I was trying to not use shampoo or use less of it, but when I train I really need it the same with soap, I don’t understand how our ancestors clean themselves without chemicals that now we have, and I don’t know if it’s a thing like washing your teeth that actually increase your life expectations.
