So here's the thing, I'm going to the most basic version of why handmade soap is better without trying to make it too scienc-y. And if you're a nerd like me, feel free to click on my resource links to learn more.
I want to appeal to you in a way that you prefer without being anti-chemical. Here's the thing, chemicals are EVERYTHING and that's not a bad thing. "Dihydrogen Monoxide," say it with me. It's water, I hope you drink enough of it! Sodium Chloride is common table salt. And Sodium Bicarbonate, that's baking soda. These are all chemicals and ones we ingest on a regular basis at that! Now I'm not saying ALL chemicals are good either, and here's where we get into the "why handmade is better" when it comes to soap. Some chemicals ARE "bad" (for human ingestion, contact, inhalation, etc.) and some, while not bad, are just unnecessary and can become harmful over time.
So let's get started, shall we?!
