Grey hair before 35? Dermatologist explain if nutrient deficiency could be the reason

Grey hair before the age of 35 has become increasingly common, particularly in urban areas. However, is this a natural occurrence or a cause for concern? Wellness advocate Tessa Pagel suggests that premature greying might be linked to mineral deficiencies. In a recent Instagram reel, she explained the connection between stress, mineral deficiency, and hair colour changes: stress depletes the minerals necessary to maintain hair pigment.

But is this conclusion medically accurate or an oversimplification? We spoke to dermatologist Dr. Shareefa Chause, from Dr. Shareefa Skin Care Clinic in Mumbai, to find out more.

While there is a clear link between premature hair greying and mineral deficiencies, genetics and aging remain the primary factors. Mineral deficiencies, such as vitamin B12, iron, copper, ferritin, and sometimes zinc, can contribute to premature greying by affecting melanin production in hair. Dr. Chause also supports Pagel's theory linking stress to greying hair.

Chronic stress can speed up hair greying by impacting melanocyte stem cells responsible for pigment production. Stress hormones and oxidative stress can harm these cells, leading to earlier loss of hair colour.

If the root cause of premature greying is solely due to mineral deficiencies, it may be reversible. Correcting nutritional deficiencies (e.g., vitamin B12) early on could potentially slow or even partially reverse the process. However, in most cases, particularly those related to genetics or age, greying is permanent. To address the issue, Dr. Chause recommends getting tested for vitamin B12, iron levels (ferritin), thyroid function (TSH), and vitamin D levels.

In some instances, zinc, copper, and a general health evaluation may also be advised to rule out any underlying causes.
