A predominant amount of pheomelanin will produce which type of hair?

The presence of a predominant amount of pheomelanin in hair is primarily associated with the production of red hair. Pheomelanin is a type of melanin that gives hair a warm, yellowish to reddish hue. In individuals with red hair, pheomelanin is more abundant, often combined with low levels of eumelanin, which accounts for black or brown shades.

In contrast, the other types of hair colors—brown, blonde, and black—are predominantly influenced by eumelanin, which comes in two forms: black and brown. Brown and black hair has higher concentrations of eumelanin and lesser amounts of pheomelanin. Blonde hair may still contain some pheomelanin, but not in predominance, as it typically results from low levels of color overall. Therefore, when we talk about a predominant amount of pheomelanin, we specifically relate it to the characteristics of red hair.
