Melanin is the molecule responsible for the many different hair color tones. It’s also responsible for the color of our skin and eyes. We inherit these traits from our parents in a complex way.
Understanding how our genetic information can produce different hair color tones can be as difficult as untangling long hair after not brushing it for several days.
Even though some genes are known to determine hair color variation, recent studies based on large cohorts of people from the United Kingdom and Latin America have shown that there are more than a dozen genes involved in hair color.
In a recent paper published in Communications Biology, my
