Question: 1 / 400

What is the effect of UV rays on hair and skin?

They can cause damage and premature aging

The effect of UV rays on hair and skin is primarily damaging and can lead to premature aging. UV rays, particularly UVB and UVA, penetrate the skin and can cause various forms of harm, including the breakdown of collagen and elastin, which are vital for maintaining skin's elasticity and youthfulness. This can result in wrinkles, fine lines, and sagging skin.

In terms of hair, UV exposure can lead to a dry, brittle texture and cause color to fade. The structural integrity of hair can be compromised, resulting in split ends and an overall lifeless appearance. Thus, while the sun is often associated with a healthy glow, the reality is that its UV rays often have an adverse effect on both hair and skin health, leading to accelerated aging and damage.

The other choices suggest beneficial effects, which do not accurately reflect the well-documented risks associated with UV exposure.
