Hair turns grey as we age due to a decrease in melanin production. Melanin is the pigment that gives hair its color, and as we age, our hair follicles produce less melanin, resulting in grey hair.
Yes, grey hair can be hereditary. The age at which your hair turns grey is largely determined by genetics. If your parents or grandparents had early grey hair, there is a higher chance that you will as well.
While there is no direct evidence linking stress to grey hair, chronic stress can lead to a variety of health issues that may indirectly contribute to the greying of hair. Additionally, stress can cause hair loss, making the appearance of grey hair more noticeable.
There is no scientific evidence to suggest that specific foods can prevent or reverse grey hair. However, a healthy and balanced diet, rich in vitamins and minerals, can help maintain the health of your hair.
Unfortunately, there is no known way to prevent grey hair. It is a natural part of the aging process and is determined by genetics. However, taking care of your overall health and reducing stress levels may help delay the onset of grey hair.
