Which type of hair is typically the result of diverse melanin involvement?

The correct choice pertains to the types of hair that result from a combination of various types of melanin, specifically the interplay of eumelanin and pheomelanin. Blond and red hair are produced by different ratios and types of melanin. Eumelanin is often responsible for darker shades, while pheomelanin contributes to lighter shades and red hues.

The presence of both types of melanin in varying amounts leads to the diverse range of blond and red hair shades. For example, red hair contains a higher concentration of pheomelanin, while blond hair has less eumelanin than darker hair colors. This complex interaction between the melanin types results in the unique and varied appearance of blond and red hair compared to the more straightforward pigmentation involved in gray, dark, and black hair, which is dominated by eumelanin levels.
