Question: 1 / 400

What effect can UV rays have on hair?

They can cause fading, dryness, and damage to the hair shaft

The effect of UV rays on hair is significant, leading to a range of detrimental outcomes. Exposure to ultraviolet light can cause the color of hair to fade, particularly in chemically treated or colored hair. This fading occurs because UV rays can break down the chemical bonds that provide pigmentation, resulting in a lighter, duller appearance.

Additionally, UV radiation can strip the hair of its natural moisture, leading to dryness. When hair becomes dry, it often becomes brittle and more prone to breakage, which compromises the integrity of the hair shaft. The damage can manifest as split ends, frizz, and overall lack of smoothness, making hair more difficult to manage.

While proper hair care can help mitigate some of these effects, UV rays remain a compelling factor in the degradation of hair health, making protective measures and products critical for maintaining hair vitality.
