Catching a glimpse of a new silver strand in the mirror can be a bit jarring, particularly if you’re on the younger side. While gray often comes with age, premature grays that appear in your 20s, 30s, or early 40s might have more to do with your body’s internal chemistry than you realize.
Although you can’t stop the clock, you can support your hair health from the inside out. One smart strategy is to make sure your body has the nutrients it needs, including key vitamins for gray hair that support healthy pigmentation and reduce oxidative stress.
In particular, nutrient depletion and stress-related damage can both influence how quickly your hair turns gray. Let’s explore the science behind what causes gray hair — and how the right vitamins, supplements like NOVOS Core, and lifestyle shifts may help slow it down.
What Causes Gray Hair?
Hair gets its color from a pigment called melanin, produced by melanocyte cells in hair follicles. People with black or brown hair have more of a pigment called eumelanin, while those with less eumelanin tend to have blonde hair. Pheomelanin, another pigment, gives hair a red color.
Hair also grows in cycles. With each new cycle, which lasts several years, melanin is produced again at the root. After seven to 15 of these cycles, melanocyte activity can decline or stop altogether, causing hair to grow gray or white.
Oxidative stress also plays a role. Over time, damaging molecules like hydrogen peroxide can build up in pigment cells, overwhelming their defenses and reducing melanin production.
Here’s a closer look at the factors that can contribute to graying and why it occurs earlier for some. For more insights, see our article How To Prevent or Reverse Gray Hair.
Premature Graying
Gray hair is expected with age, but premature graying — typically defined as before age 20 in Caucasians, 25 in Asians, and 30 in African populations — can point to underlying issues, like nutritional imbalances or chronic stress.
Stem Cell Mobility
A 2023 study in Nature found that melanocyte cells have the unique ability to shift between different compartments in the hair follicle as hair grows and regenerates. This mobility is essential for maintaining hair color. But as we age, more of these cells become “stuck” in one part of the follicle. Essentially, they lose the flexibility needed to mature and produce pigment, causing gray hair.
Genetic Influence
Genes play a role — some people are simply wired to go gray earlier. A 2023 review in Ageing Research Reviews highlights that variants in genes related to pigment production, stem cell survival, and oxidative stress can all influence when graying begins.
Stress, Environment & Diet
Factors like stress, sun exposure, and poor nutrition can speed up the graying process, even if you’re not genetically prone to early graying. Next, we’ll look at vitamins for gray hair and how simple shifts can help support the systems that keep pigment-producing cells functioning longer.
Can Vitamins Slow Premature Graying? Diet, Lifestyle & Environmental Factors
No vitamin is guaranteed to turn gray hair back to its original color once melanocytes have stopped producing pigment. However, in some cases, the right nutrients and healthy habits may help slow the process — especially when graying is linked to nutritional deficiencies, lifestyle factors, or environmental stressors.
Diet & Nutrients
Nutritional factors can influence whether gray hair appears early. Research suggests that deficiencies in certain vitamins and minerals may accelerate premature graying. Among them:
- Vitamin B12: A review published in 2024 found that low vitamin B12 can interfere with how hair cells grow and renew. B12 helps keep hair in its active growth stage and supports the cells that generate pigment.
- Iron: Iron plays a role in the enzymes that make melanin, the pigment that colors hair. Some research suggests an iron deficiency may contribute to premature hair graying, although further research is needed for a definitive link.
- Copper: Copper is a cofactor for tyrosinase, a key enzyme in melanin production. Studies have linked low copper levels with premature graying.
- Calcium and vitamin D: A 2025 review found that people with premature graying often had lower calcium and Vitamin D3 levels.
Overall, maintaining a balanced, nutrient-rich diet with adequate vitamins and minerals may help lower the risk of premature graying.
Lifestyle and Environmental Factors
Your daily habits and surroundings matter, too. Studies show that:
- Smoking and alcohol increase oxidative stress, which may contribute to earlier graying.
- A sedentary lifestyle may speed up the process. In contrast, regular exercise and moderate sun exposure support healthier hair pigmentation.
- Hair plucking and harsh chemical treatments (like frequent dyeing or perming) can damage follicles, deplete melanocytes, and promote graying.
- Environmental exposures — like too much UV light, radiation, or air pollution — can create oxidative stress that damages hair pigment.
Combining Vitamins for Gray Hair With Healthy Changes
The right vitamins for premature gray hair can help you correct deficiencies in key nutrients like B12, copper, and vitamin D. This proactive step may help preserve pigment, especially if you act early.
Quitting smoking, getting regular exercise, and protecting hair from environmental damage can also reduce the oxidative stress that drives graying.
That’s why many longevity experts recommend combining supplements with lifestyle changes. For example, NOVOS Core contains compounds like vitamin C, magnesium, and glycine, which help combat oxidative stress and support cellular health throughout the body.
Keep in mind that results depend on the individual and how long it’s been since the follicles stopped producing melanin.
A Longevity-Based Approach to Hair Health
Hair graying isn’t just a cosmetic issue; it reflects broader signs of biological aging. That’s why a longevity-first lifestyle may be your best holistic defense against aging in general. Supporting cellular health through diet, stress reduction, sleep, and targeted supplementation can go a long way toward helping you live healthier for longer.
NOVOS Core is formulated to address multiple hallmarks of aging, not just gray hair. While it’s not a gray-hair supplement per se, several of its ingredients are tied to healthy hair growth and melanin support:
- Magnesium: Essential for DNA repair and energy production in hair follicles
- Vitamin C: Boosts iron absorption and supports collagen synthesis for strong, healthy hair
- Glycine: An amino acid critical for structural proteins like collagen
- Alpha-ketoglutarate (AKG): May improve mitochondrial function and reduce oxidative stress, as shown in animal research
- Hyaluronic acid: Helps support skin and scalp hydration
Together, these compounds work to improve both healthspan and lifespan — and your hair enjoys the benefits.
FAQ About Vitamins for Gray Hair
What vitamins reverse gray hair?
While no vitamin is guaranteed to reverse graying, getting adequate levels of vitamin B12, folate, copper, and iron may slow the process if deficiencies are the root cause.
What vitamin deficiency causes gray hair?
Vitamin B12 deficiency is one common culprit. Copper and iron deficiencies have also been associated with early graying.
What are the main causes of gray hair?
Aging, genetics, oxidative stress, and nutritional deficiencies. Lifestyle stress and environmental toxins can speed up the process.
