Hair color is determined by the amount and type of melanin present. While often correlated, hair color on the head and eyelashes isn’t always identical. Individuals with blonde hair can have eyelashes ranging in color from very light blonde, almost translucent, to shades of brown. This variation stems from genetic factors influencing melanin production in different hair follicles.
Understanding the relationship between genetics and pigmentation offers valuable insights into human biology. Research in this area contributes to knowledge about genetic inheritance, phenotypic expression, and potential health implications related to melanin levels. This knowledge has implications for fields like dermatology and cosmetics.
