10 Causes That Make Your Hair Turn Grey

If you're in your mid-20s and already noticing grey strands at your temples, don’t worry—you’re not alone. Premature greying has become a common concern among the younger generation. While grey hair is often seen as a sign of ageing, age isn’t always the root cause. In fact, the reasons behind early greying can be quite different.

The primary biological reason for greying hair is the reduction of melanin—a pigment responsible for hair colour. Normally, melanin levels decrease as we age. However, nowadays, many people experience premature greying due to an accelerated loss of melanin. Several factors can trigger this early depletion.

To effectively address premature greying, it’s important to first understand its underlying causes. Here are some common reasons your hair might be turning grey before its time:

# Genetics

Early greying often runs in families. If one or both of your parents started greying young, chances are you might too.

# Vitamin B12 Deficiency

A lack of vitamin B12 can accelerate melanin loss in your hair. The good news is this condition is reversible with the right intake of B12.

#. Thyroid Disorders

Both hypothyroidism and hyperthyroidism are linked to premature greying. With thyroid issues becoming increasingly common in youth, they’re a significant factor to consider.

# Hormonal Imbalances

Many women experience greying hair during pregnancy, mainly due to fluctuating hormone levels.

# Pituitary Gland Dysfunction

The pituitary gland regulates growth and development. If it isn’t functioning properly, it can speed up ageing, including hair greying.

# Iodine Deficiency

Iodine, though required in small amounts, is essential. A deficiency can lead to early greying, especially around the temples.

# Anaemia

A lack of red blood cells can leave you feeling tired and weak—and may also manifest as grey hair, indicating poor health.

# Malnutrition

Poor nutrition is a major contributor to premature greying. When your body lacks essential nutrients, the ageing process—including hair greying—can accelerate.

# Copper Deficiency

Copper helps maintain healthy hair pigmentation. Insufficient copper can lead to white, brittle strands.

# Stress and Anxiety

Chronic stress disrupts blood flow and nutrient supply to hair follicles, making stress one of the leading causes of premature greying.
