* Brown hair: Globally, brown hair is the most common natural hair color, with a large percentage of the world's population having brown hair.
* Black hair: Black hair is another highly prevalent natural hair color, especially in certain regions of the world.
* Blonde hair: While less common naturally, blonde hair is often associated with beauty and desirability in many cultures, making it a popular choice for hair dyeing.
