Genetics, Not Stress, Causes Early Grey Hair

Premature hair greying, often noticed in one's early twenties, is commonly attributed to stress in India. However, experts clarify that genetics are the primary driver, with nutritional deficiencies and lifestyle factors potentially accelerating the process.

Medical evaluation is recommended only if greying appears suddenly or is accompanied by other symptoms, such as thyroid disorders. The definition of early greying varies by ethnicity, with earlier onset considered before 25 for Asians, reflecting genetic variations.

While stress alone doesn't turn hair grey, chronic stress can indirectly affect pigmentation by disturbing hormonal balance. Factors like smoking, pollution, and deficiencies in iron, B12, copper, and folate can also contribute.

Reversing genetically driven grey hair is rare, though correcting deficiencies or stress-related factors may slow progression. Experts emphasize that early greying is predominantly a natural biological process rather than a cause for significant concern.
