Why are gray hairs more coarse than my natural hair?Updated 5 hours ago

As hair turns gray, it's not just the color that changes. The loss of pigment can alter the structure of the hair fiber, making it feel coarser, drier, or more wiry. Aging follicles can also produce hair that grows in with a different shape and texture. Gray hair also becomes more vulnerable to UV damage, since pigment naturally helps protect the hair fiber.
