What is the main function of melanin in the body?

Repairs skin cells
Provides color to skin and hair
Protects against sun damage
Stimulates hair growth

The correct answer is: Provides color to skin and hair

The primary function of melanin in the body is to provide color to the skin, hair, and eyes. Melanin is a pigment produced by melanocytes, which are specialized cells found in the skin and hair follicles. This pigment is responsible for the various shades of skin and hair color. Additionally, melanin plays a critical role in protecting the skin from UV radiation by absorbing harmful sun rays. This protective ability is important for reducing the risk of sun damage and skin cancers, contributing to the understanding of why the production of melanin can increase in response to sun exposure. While repairing skin cells and stimulating hair growth are essential functions in the body, they are not directly attributed to melanin. Instead, these processes involve different biological mechanisms and cells. Thus, the provision of color to skin and hair is the most accurate depiction of melanin's primary function.
