-
Hormone levels fluctuate rather than decline smoothly
-
Hair follicles in certain areas (ears, nose, eyebrows) become more sensitive to testosterone
-
These follicles start producing coarser, darker, longer hair
Interestingly, while scalp hair may thin due to hormone sensitivity, ear and nose hair follicles often react in the opposite way, becoming more active.
This is why many people joke that hair “moves” from the head to the ears—but biologically, it’s about how different follicles respond to the same hormones.
Aging Changes How Hair Grows
Aging doesn’t just affect wrinkles and joints—it also changes how hair behaves.
As the skin ages:
-
Hair growth cycles slow down
-
Shedding becomes less frequent
-
Hair stays in the growth phase longer

Grow longer than before
-
Appear thicker and wirier
-
Stick out instead of lying flat
At the same time, the skin around the ears becomes thinner, making hair more visible even if the amount hasn’t changed much.
