It is a common myth that greying of hair is caused by stress or anxiety. While psychological stress can aggravate certain medical conditions that may result in premature greying, it is not the sole cause of grey hair. The true cause of grey hair is the natural aging process.

As we age, our hair follicles produce less melanin, the pigment that gives hair its colour. Melanin helps to protect the scalp from the sun’s ultraviolet rays, so when melanin production decreases, the hair turns grey. This process is gradual and usually starts at around the age of 30.

Genetics play an important role in the onset and rate of greying. People from certain ethnic backgrounds are more likely to go grey at a younger age than others. For example, Asians tend to go grey at a younger age than Caucasians.

As well as genetics, there are other factors that can contribute to greying. Smoking, poor nutrition, and too much exposure to the sun can all cause premature greying. Hair products that contain harsh chemicals can also strip the hair of its natural colour.

If you are worried about grey hair, it is important to eat a healthy diet, take regular exercise and limit your exposure to the sun. If you are a smoker, try to quit. You should also avoid using hair products that contain harsh chemicals.

In summary, premature greying is usually caused by the natural aging process. Genetics and lifestyle choices can also play a role. If you are worried about grey hair, it is important to make healthy lifestyle choices and limit your exposure to the sun.
