Hairred

Hairred refers to a hair color that falls within the spectrum of red. This can range from subtle auburn or coppery tones to vibrant, fiery crimson shades. Natural red hair is relatively uncommon, with estimates suggesting it occurs in only 1-2% of the global population. The gene primarily responsible for red hair is the MC1R gene, which influences the production of melanin, the pigment that colors hair, skin, and eyes. Variations in this gene lead to a higher proportion of pheomelanin, a reddish pigment, and less eumelanin, a darker pigment.

Individuals with naturally red hair often have fair skin, freckles, and a higher sensitivity to UV radiation. Their hair color can also vary in intensity and hue throughout their lives. While natural red hair is characterized by its unique pigment composition, artificial red hair colors are achieved through dyeing processes using various chemical and natural dyes. These can create a wide array of red shades to suit personal preference. The cultural perception of red hair has varied throughout history and across different societies, sometimes being associated with magic or rebellion, and at other times with beauty and passion.
