Hello! Dad wants me to write an essay on why does the color of your hair change as you age? The reason I am doing this project is because one of our Jersey cross bottle Calf was very light brown when he first came to the farm then his hair started turning black! So I wondered why this was happening and dad said I should do research on it and write an essay on it! So here I am!
Here is what I found!
The amount of eumelanin pigment determines how dark our hair is. The genes for making melanin might turn on or off over the course a person’s lifetime. If this happens in the cells at the bottom of your hairs, your hair might change color! Cool right? So maybe the pigment was changing on that calf because the cells at the bottom of his hairs were not working!

That’s it hope you enjoyed!
