A new animal study suggests that certain stem cells have the unique ability to move between the growth zones of hair follicles. However, as we age, these stem cells become stuck and lose their ability to mature and maintain hair color. This discovery potentially opens up new opportunities for scientists to explore natural approaches to delaying the onset of gray hair.
Why Does Hair Turn Gray?
Have you ever wondered exactly why our hair turns gray as we get older? Although we have a variety of hair colors during our youth, once we age, our hair inevitably turns the same color.The natural color of our hair is determined by a pigment called melanin, which is produced by melanocytes, cells located at the base of hair follicles. They produce two types of melanin: eumelanin, which is responsible for brown or black hair, and pheomelanin, which creates blond or red hues. The balance between these two types of melanin determines the final color of our hair.
