Don't a lot of people make their own products already? Those who don't make their own or are too lazy (like me!
) will buy the product either way because it's easier. They also wouldn't have to worry about anyone stealing and selling their product if they get a patent or it's patent pending, right? Not sure if this is true. I don't think they would lose that much business because those who are going to make their own products are going to do it anyways. Also, I think that the only way to save money making these products is to buy in bulk. Buying smaller amounts would be more expensive and you might end up spending the same amount as if you just bought it from the seller in the first place (in some cases, depending on the seller and how much they charge).
And to the OP, I wouldn't buy. I don't know a lot about natural hair care, but how do I know that what they claim is true? What's their definition of, "natural?" I'm a consumer, not a producer, and if I like a product I would buy it even if I did know all of the ingredients and could make it myself.
