Why does the sun make our hair lighter but make our skin darker?
user
Because of the way our hairs and skin respond to sun exposure, repeated tanning can cause our skin to become darker, while our hair gets lighter. This is because melanin, the pigment that gives color to our skin and hair, is produced more in sunlight. The darker-skinned individuals have higher baseline levels of melanin production than light-skinned people. Over time, repeated sun exposure will cause their hair to bleach and lighten but their skin will become progressively darker.

Why does the sun make our hair lighter but make our skin darker?
user
Sunlight contains a spectrum of wavelengths, and the type of light responsible for lightening hair is in the blue to violet range. This type of light has been found to cause melanin, which is the pigment that gives our hair and skin color, to break down over time resulting in lighter hair. However, while our hair may become lighter with prolonged exposure to sunlight, our skin will eventually become tan or brown as a result of an increase in melanin production due to UV radiation.
