The Fischer-Saller scale, used in physical anthropology and medicine, identifies a variety of shades on the spectrum between light and dark, red and brown. Human hair color comes in a variety of shades depending on the particular mix and concentration of pigments. Mixes of eumelanin and pheomelanin lead to auburn or strawberry blonde hair. All humans have some pheomelanin in their hair, but true redheads have little to no eumelanin. Pheomelanin causes hair to look red or orange. A subtype of eumelanin makes hair black (interestingly, smaller concentrations of this subtype results in white hair). Smaller amounts of eumelanin make a person’s hair blonde, while larger concentrations make it brown.

Two types of pigment give hair its color: eumelanin and pheomelanin.Įumelanin makes hair brown or black hair, and the amount of eumelanin present determines how dark the hair is. Generally, we see light hair earlier in life and dark hair towards adulthood.

A single person may have different color hair at different ages. Not only that but the amount of melanin present changes throughout life. So we are not really looking at completely separate hair color genes, but rather differing amounts of the same kind of pigment: melanin. Hair gets its color from pigment, and the amount of pigment in the hair affects its exact shade. In truth, the genetics of hair color is just a little more complicated than your basic biology class might claim.
