As time passes and youth fades, a lot of inevitable changes occur in the skin and hair. Yes, many of us are familiar with and understand why wrinkles, creases, and other changes emerge as we age, but most of us do not understand why we go grey, especially when we do not believe we are that old. Why does hair age at a faster rate than other parts of the body? In other words, why are older, darker hairs rapidly replaced by grey ones when we age, when many other old cells are still constantly being replaced by healthy, regenerated cells?
Well, as we grow older, our hair naturally turns grey or white, and this happens as a result of the cells that produce pigment, known as melanocytes, diminishing in number and function with time and age. These melanocytes, which are important for giving hair its colour, decline when their activity declines, and melanin synthesis slows down, causing hair to appear grey or white.
However, the process of hair greying or whitening is not the same for everyone. There are several factors that can influence the rate and extent of this process. Genetics play a significant role, as hair colour is determined by our genes. If our parents or grandparents experienced premature greying or whitening of hair, there is a higher likelihood that we would also experience the same. Certain medical conditions, such as thyroid disorders and vitamin deficiencies, can also contribute to premature greying or whitening.
Furthermore, lifestyle decisions and environmental factors can accelerate the ageing process of going greying or hair whitening. Pollution from the environment, such as air pollution, cigarette smoke, and the like, can impair and accelerate melanocyte degeneration. In addition, persistent stress and poor eating habits, such as a lack of nutrition, might have an impact on melanocyte formation.
It’s important to note that greying or whitening of hair isn’t always a clear sign of bad health or old age. It’s a normal part of the ageing process. Many also associate the greying or whitening of hair as a sign of wisdom and life experience. There are things that may be taken to reduce or prevent premature greying or whitening, though.
Maintaining a healthy lifestyle, managing stress, and eating a well-balanced diet are all beneficial to maintaining hair and melanocytes in their optimal state. Regular exercise, sufficient sleep, and avoiding excessive heat styling and chemical treatments are all great ways to maintain the colour and shine of your hair. Furthermore, using hair care products specifically developed for hair, such as those containing nourishing components like vitamins and antioxidants, may be useful.
