I am seeing more and more grey hair, although I am not that old.
Does your scalp age? Yes, our scalp is also part of our body, made up of skin. Studies have shown that our scalp ages the fastest – 12 times faster than the skin on our body and 6 times faster than skin on our face. external factors can speed up the rate of aging of our scalp. This results in the thinning of our scalp with lesser blood capillaries thus lowering nutrient and blood supply to the follicles.
We are surrounded by UV radiation and air pollutants, and at the same time extensive styling creates stress on our scalp which actively contributes towards the aging of our scalp. But as our scalp is covered by hair, we tend to neglect our scalp much more than our body or face skin. Our hair growth is about 1.25cm per month on a healthy scalp, but on an aging scalp, it is only 0.25cm per month, which is 80% less! Our hair follicle function also naturally diminishes over time, and each follicle has 25 cycles in its lifetime.
As a result, grey hair is one of the sign of aging as the hair follicles produce less melanin, the pigment that gives black colour to our hair.
