Hello, I'm a genetics expert with a focus on how genetics influence physical traits. Let's dive into the reasons behind why you might have brown hair.
Hair color is determined by the amount and type of pigments in the hair. The primary pigment responsible for hair color is melanin, which comes in two forms: eumelanin and pheomelanin. Eumelanin is responsible for black and brown hair, while pheomelanin is responsible for red and yellow hair.
The specific shade of brown your hair is can be attributed to the genetic factors you've inherited from your parents. Hair color is a polygenic trait, meaning it's influenced by multiple genes. These genes control the production and distribution of melanin in your hair follicles.
Moreover, the expression of these genes can be affected by various factors, including your age, health, and even environmental influences. For example, as people age, they may notice their hair becoming less vibrant and more gray or white, which is due to a decrease in melanin production.
In summary, the brown color of your hair is a result of the melanin present in your hair and the genetic instructions you've received from your parents that determine how much melanin is produced and how it's distributed in your hair.

Brown hair is the second most common human hair color, after black hair. It varies from light brown to almost black hair. It is characterized by higher levels of the dark pigment eumelanin and lower levels of the pale pigment pheomelanin.
