That's a very good question to ask of anyone telling you about ingredients! I try very hard to make sure anything I say about any ingredient I've researched from an objective source.

But I know that anyone can say they've researched ingredients, so for almost every ingredient I mention (and I'm working on making it every single ingredient), I put the exact source I use, as well as the page number(s) so anyone can look up my source and decide for themselves if they trust the ones I use. I try to use multiple sources to check out an ingredient, and list every one I do use in the description. I also post all the sources I use at the bottom of the Ingredients Dictionary page so you can check those out too.

It's very smart to question where someone is getting their information from. Many times people have heard something is bad for their hair or good for their hair so many times it starts to sound like it's fact, when actually, it isn't. Much information that's put out there is from the manufacturers of lines of products that charge a high price for "exotic" ingredients. And in order to justify their price, they have to make perfectly good, affordable ingredients sound terrible. And many of these products are loaded with highly irritating ingredients that do nothing for our hair, but are marketed as being healthy. So it's wise to check out your sources, both for the sake of your hair, your skin, and your wallet.
