Whether it’s due to quick access to information, constant experimentation with products, or their fast-paced lifestyles, Generation Z is showing signs of aging earlier than expected.

One of the most common concerns is their gray hair, and even millennials struggle with this problem. The concern about the appearance of gray hair is increasing among people in their 20s and 30s.

If you are also worried about premature graying of hair, then know from the experts why this is happening and whether the problem of premature graying of hair can be prevented.

Understand the what and why

“Premature graying of hair, also known as caninities, occurs when the hair begins to turn gray before the age of 20 in Caucasians, before the age of 25 in Asians, and before the age of 30 in African-Americans,” explains Mumbai-based dermatologist Dr Aparna Santhanam. india today,

According to Dr DM Mahajan, senior consultant of dermatology at Indraprastha Apollo Hospital, New Delhi, the primary causes of premature greying of hair include genetic predisposition, which accounts for about 30 per cent of cases, as well as environmental factors such as oxidative stress, ultraviolet radiation and pollution.

Nutritional deficiencies and certain medical conditions, such as vitiligo, alopecia areata, and thyroid disorders, can also cause premature graying of hair.

“Modern lifestyle choices, including poor diet, smoking and alcohol consumption, can increase oxidative stress and impact hair colour,” says Dr Shitij Goyal, Head, Department of Dermatology, NCR-based Sharda Care.

Dr Goyal explains that millennials and Generation Zers are experiencing premature graying of hair due to a mix of modern lifestyle choices, environmental exposures, dietary habits, and genetic predispositions. They often face high stress levels, irregular sleep patterns, and poor nutrition, all of which can accelerate the graying process.

Lifestyle is a major factor

“Lifestyle plays a major role when it comes to premature greying of hair, especially in a fast-paced urban environment,” says Dr Rachana Shilpakar, Consultant Dermatologist, Rainbow Children’s Hospital, Bengaluru.

The pressure to achieve top ranks, meet office deadlines, and cope with a sedentary, screen-bound lifestyle, combined with poor sleep, is increasing oxidative stress.

The growing trend of fast food has made this problem worse, leading to widespread problems like nutrient deficiencies, obesity and metabolic syndrome, making this problem spread like wildfire.

blame the stress

It is important to understand that chronic stress triggers the secretion of norepinephrine, which makes melanocyte stem cells overactive and depletes the reserves of pigment-producing cells. This reduces the production of melanin, leading to graying of hair.

Additionally, stress-induced hormonal changes can affect hair growth cycle and pigmentation.

However, Dr. Santhanam says that once the hair turns grey, reducing stress alone cannot naturally restore it to its original colour. Controlling stress can prevent further greying and help maintain overall hair health.

Stress management techniques, such as mindfulness, meditation, regular exercise, and adequate sleep, can help reduce the effects of stress on hair color.

“In some rare cases, especially if the greying is due to stress and is detected very early, a small percentage of people may see some colour return to their hair after a significant reduction in stress. However, this is uncommon,” says Dr Mahajan.

Smoking and vaping are not good

Experts insist that smoking and vaping are responsible for premature gray hair because they cause oxidative stress and reduce blood flow to hair follicles, which damages melanocytes. The toxins in tobacco also disrupt melanin production, leading to gray hair.

Let’s talk about nutrient deficiencies

Dr. Mahajan explains that along with vitamin and mineral deficiencies, hormonal imbalances can also cause premature graying of hair.

“Low levels of iron, copper and vitamin B12 are particularly associated with early graying of hair. Iron is important for DNA synthesis in hair follicles, while copper is essential for melanin production. Vitamin B12 deficiency can lead to pernicious anemia, which affects melanin synthesis,” he said.

Thyroid imbalances such as hypothyroidism and hyperthyroidism can also disrupt the hair growth cycle and pigmentation.

To overcome these shortcomings, a comprehensive approach is needed:

• Complete medical evaluation, including blood tests, to identify specific deficiencies or hormonal imbalances.
• Targeted supplementation under medical supervision to correct deficiencies.
• Dietary modifications to include nutrient-rich foods for long-term management.
• Proper medication and regular monitoring are necessary for thyroid problems.

In some cases, addressing these underlying factors can help prevent premature graying, especially if caught early.

Can this be reversed?

“Premature graying of hair can sometimes be reversed if the cause is due to correctable factors such as nutritional deficiencies, thyroid imbalances, or oxidative stress,” says Dr. Goyal.

However, Dr. Santhanam points out that though premature greying of hair cannot be completely prevented, greying of hair can be slowed down by addressing the underlying causes.

Dr. Mahajan agrees, and says that while complete reversal isn’t usually possible, certain methods may help slow its progression or restore some color in some cases.

Topical treatments that prevent gray hair, such as catalase, copper peptides or melanin-stimulating compounds, aim to reduce oxidative stress and support melanocyte function. These may be worth a try, but they are more effective as preventive measures than as treatments for reversing gray hair. Results can vary widely depending on individual responses.

In addition to topical treatments, oral medications and supplements can also be effective. Traditional remedies such as amla, curry leaves and henna are also worth trying.

However, it is also important to accompany these treatments with lifestyle changes, which include stress management, eating a balanced diet, avoiding smoking and environmental pollution.
