Hair protector sun, a noun, refers to solutions that protect hair from damage caused by the sun's ultraviolet radiation. These products can come in the form of leave-in treatments, UV-blocking mists, and even hats and scarves.
Hair protector sun is important because the skin on the scalp is particularly sensitive to sun damage, and the hair itself can become dry, brittle, and discoloured. Hair protectors block and absorb UV rays, preventing them from damaging the scalp and hair.
