We have pigment cells in our hair follicles. As we start to age, these pigment cells start to die. As these pigment cells die, the strands of hair no longer contain as much melanin and will change colour to either grey, silver, or white as it continues to grow.
The rate at which grey hair appears is down to our genes, and we have no control over those. This means that for most of us, we will start to get grey hairs around the same age that our parents or grandparents first did.
Is it possible to reverse grey hair on your beard? Before exploring potential solutions, it's important to understand the science behind grey hair.
Hair colour is simply determined by the amount of melanin in the hair follicle. Melanin is a pigment that gives colour to our skin, hair, and eyes. As we age, the melanin production in hair follicles decreases, leading to grey hair. This is due to a decrease in the number and activity of melanocyte cells, which produce the pigment.
Age-Related Changes in Hair Pigmentation
While grey hair is often associated with aging, it can also be caused by other factors such as genetics, stress, health conditions, and environmental factors. In some cases, hair may turn grey prematurely, before the age of 20. Understanding the causes of grey hair can help us determine if it's possible to reverse it.
