Question: 1 / 400

What can excessive sun exposure do to the hair?

It can heal damaged hair

It can lead to dryness, discoloration, and brittleness

Excessive sun exposure can indeed lead to dryness, discoloration, and brittleness in hair. The ultraviolet (UV) rays from the sun can strip the hair of its natural oils and moisture, which are essential for maintaining healthy and vibrant hair. As the hair becomes more dehydrated, it suffers from a lack of elasticity and strength, leading to breakage and a dry, frizzy appearance.

Furthermore, UV rays can alter the pigment in the hair, resulting in discoloration—particularly in colored or treated hair. This can lead to changes in the tone and brightness of the hair, making it look dull and lifeless over time. In summary, the damaging effects of prolonged sun exposure on hair are significant and can severely impact its overall health and appearance.
