According to The University of Rochester Medical Center, beef tallow contains an abundance of vitamin E, and Healthline says, “A vitamin E-rich oil can help replace that protective layer and bring back shine. Oil in general also helps seal moisture, reduce breakage, and protect the hair from damage.”
There are many beauty products on the shelves that say they contain vitamin E, but there is a good chance it could come from synthetic sources. There are different names for vitamin E that indicate whether it is natural or synthetic, but it always comes down to trust.
The FDA admits that “cosmetic products and ingredients do not need FDA premarket approval, with the exception of color additives.”
In other words, cosmetic companies could easily get away with lying about the source of vitamin E in their products. They could tell you it is naturally sourced when it is actually synthetic. If they get caught lying, then they may face fines or other consequences, but until then, trusting a cosmetic company with your skin is a gamble.
The problem with synthetic vitamins is that they are made in a lab with harsh chemicals, and the body has a harder time absorbing them. What’s more, any amount of those chemicals that your skin does manage to absorb could be dangerous to your health when used in the long term!
Given this information, you may want to use beef tallow for vitamin E on dry hair, because you can trust that it is as safe as it is effective.
The reason I use so many edible things on my hair is because I am confident of the quality of nutrients, I know exactly what is in it, and I know exactly where it came from!
