Turns out, its all to do with our sexhormones. The level of hormones present in our body, such as testosterone and estrogen, regulate the activity of our melanocyte cells. These are the cells in our skin and hair that release melanin, the protein pigment responsible for our skin color. Production of these rampupwhen we made puberty, hence why these dark areas merely appear to emerge when we get older.
Hormones govern the style melanocytes render their pigment, ” saidDr. Rokhsar.”Those can have an effect on the way the scalp in that area pigments, so generally that area is darker.”
