Here's why:
* Sun exposure and melanin: Sunlight contains ultraviolet (UV) radiation. UV rays break down melanin, the pigment that gives hair its color.
* Strawberry blonde hair: Strawberry blonde hair is naturally a mix of light blonde and red pigments. The red pigment is more sensitive to sunlight and will fade faster.
* The result: When strawberry blonde hair is exposed to the sun, the red pigment fades more quickly than the blonde, leaving the hair with a more golden or light blonde appearance.
So, the sun won't turn strawberry blonde hair into a different color, but it will lighten it, making it appear more blonde and less red.
