Go on Amazon, Google, or TikTok Shop and scroll, they're all the same. Almond Oil, Argan oil, and Avocado oil (maybe rosemary oil if they're trying to be unique). Different bottles, different labels, but the formulas are all virtually identical, it's all snake oil.
These companies invest NOTHING into research or innovation, they do the bare minimum. They're just repackaging the same formula from decades ago with slightly different doses or one new ingredient, that's why no matter what beard growth oil you try they all don't grow you a beard.
Whether you spend $20 or $200, you're getting the same basic oil that barely outperforms placebo in clinical studies.
