While grey hair is typically equated with aging, recent findings show that it could serve as a barometer for serious health issues. Genetics plays a huge role in when hair turns grey, but an increasing number of studies are finding that underlying health issues such as issues with the thyroid, heart issues, and dietary deficiencies can be just as big of factors contributing to premature greying.
An imbalance in the thyroid (hypothyroidism or hyperthyroidism) can inhibit melanin production in hair follicles ultimately causing premature greying. The thyroid is critical for metabolism and hair growth and pigmentation; therefore the result of an imbalance is loss of pigmentation, thinning, and drying before old age sets in. Treat the thyroid condition with appropriate medical supervision, and the patient may on occasion reverse this loss.
The health of our cardiovascular system is also linked to pigmentation of our hair. There are studies that show premature greying may suggest increased cardiovascular risk as an early marker independent of age or family history that could potentially be linked by shared causal pathways (i.e. oxidative stress, or vascular aging).
Diet can also be another factor. Low intake of vitamin B12, iron, copper, zinc, and folic acid can all influence the amount of melanin and thus loss of pigmentation, which leads to grey hair. It is important to stress the need to eat a well-balanced diet with good nutrition to maintain good hair health overall, but also might be indicative of potential risk for grey hair and other age-related issues, or if a person can replete the deficiency, then the colour pigment can sometimes be restored early in the event.
In conclusion, although one will likely see a more grey hair with increased age, in some circumstances, it can also be a significant biologic marker supporting potential underlying issues related to thyroid, heart, or just nutrition. Monitoring your health, seeing your family physician for check-ups, and eating well may be important for a few to delay or prevent grey hair.
