Hair color, or the pigmentation of human hair, encompasses a wide range of hues and tones, from the darkest black to the lightest blond. It is primarily determined by genetics, but can also be influenced by environmental factors and lifestyle choices. For example, sun exposure can lighten hair, while certain hair treatments and dyes can alter its color.
The diversity of hair colors has significant cultural and societal implications. Different hair colors have been associated with various stereotypes and beliefs throughout history. In some cultures, dark hair is perceived as a sign of strength and power, while light hair is associated with beauty and innocence. The development of hair dyes in the early 20th century revolutionized the hair industry, allowing individuals to experiment with different hair colors and express their personal style.
