As a subject matter expert in genetics and human physiology, I can provide an informed perspective on the relationship between hair color and sensitivity to cold.
Hair color is determined by the amount and type of pigments in the hair follicles, which are influenced by genetics. Red hair is caused by a specific variant of the MC1R gene, which produces a pigment called pheomelanin. However, the idea that redheads are more sensitive to cold is not directly supported by scientific evidence.
The sensitivity to cold is more closely related to factors such as body composition, blood circulation, clothing, and acclimatization to the environment rather than hair color. For example, people with more body fat may feel less cold because fat acts as an insulator. Additionally, individuals who are more active and have better blood circulation may feel less cold because their bodies generate more heat.
It's also important to note that the perception of cold can be subjective and vary from person to person. Some studies suggest that people with lighter hair colors might have a slightly higher number of melanocytes (cells that produce pigment) in their skin, which could potentially affect their sensitivity to the sun, but this does not necessarily translate to a heightened sensitivity to cold temperatures.
In conclusion, while there is a genetic basis for hair color that affects the type of pigment produced, there is no scientific consensus that links hair color directly to an increased sensitivity to cold.

Researchers think that the ginger gene, known as MC1R, may cause the temperature-detecting gene to become over-activated, making redheads more sensitive to the cold. ... That redheads are subject to sunburn and skin cancer must be linked to the difference in pain sensitivity."
