Why Your Hair Is Already Turning Gray And What You Can Do About It

From the haircare products we use to the nutrients we nourish our body with and the ticking biological clock we can't ignore, there are several explanations for why those pesky gray hairs start showing up in our mid-twenties or early thirties.

However, the exact chemical reactions or processes in our body that lead to graying hair are a little more complex than we may think. And with new studies suggesting that many of these could result from our lifestyle habits and choices, there is a glimmer of hope that reversing something that has been deemed irreversible for so long may not be entirely impossible.

Behind the Silver Strands: Understanding Why Our Hair Turns Gray

In order to understand how to prevent our hair from turning gray when many of us hit our mid-twenties, we need to understand what causes this occurrence in the first place.

According to dermatologists, our hair turns gray due to a decrease in melanin, a natural pigment produced by special cells called melanocytes that are responsible for giving our hair its unique color.

As we age, our body produces less and less melanin due to the cells that make this pigment naturally maturing and their activity slowing down or potentially reacting to the years of chemical accumulation in our bodies that eventually take a toll on their functionality. When these cells become sluggish and slow, the melanin production decreases, ultimately resulting in less pigmentation and, thus, graying hair.

Is Graying Hair Just Genetics or Something More?

While genetics play a role in when and how much gray hair we develop at any point in our lives, there's undoubtedly more to the story if you take the above explanation on how the pigment that gives our hair its color into consideration.

As we already mentioned, the cells that produce our hair pigment can, like pretty much everything else in our body, become damaged due to multiple factors. Some of these include oxidative stress, chemical accumulation, and hormonal changes – which, coincidentally, can be connected in various ways. So, let's start by explaining what all of these mean and how they may contribute to the graying of our hair.

Oxidative stress occurs when there is an imbalance between free radicals, which we naturally produce through metabolism, and the antioxidants that keep them in check. When this balance is disturbed, free radicals start damaging cells in our body, including the melanocytes responsible for producing melanin.

Chemical accumulation that may result in graying hair can be attributed to years of using haircare products such as dyes, bleaches, or styling products that contain bleaching chemicals such as hydrogen peroxide, which has been found to affect the production of melanin. This results from the enzyme catalase, which breaks down hydrogen peroxide in our bodies, slowing down with age and allowing the chemical to accumulate and affect the melanocyte cells via oxidative stress.

Cortisol can affect the regeneration of hair pigment by creating oxidative stress that damages the stem cells responsible for producing melanin.

Lastly, hormonal changes, particularly during prolonged times of stress, can further compound these effects. Several studies have linked cortisol, which is the stress hormone, to significant changes and decreases in melanin production in the body. Namely, it has been suggested that cortisol can affect the regeneration of hair pigment by creating inflammation and oxidative stress in the body and damaging the stem cells responsible for producing melanin. This again emphasizes the impact of oxidative stress on melanocytes and the acceleration of the onset of gray hair.

So, while genetics set the stage for graying hair, internal and environmental factors, chemical accumulation, and hormonal shifts intricately interact to accelerate this particular symptom of the natural aging process.

What About Our Diet?

While we can't influence all of the factors that bring up specific changes we may deem unattractive, such as graying hair or wrinkles, we are far from helpless in controlling how our bodies age.

Now, instead of stocking up on hair dye, panic buying root touch-up sprays, or turning to TikTok for the latest gray hair-reversing trends, another solution may be even more effective and long-lasting: a nutritious diet.

In fact, many studies have linked prematurely graying hair to nutrient deficiencies, particularly vitamins B12 and D3, copper, and calcium. These nutrients are so crucial because they all play a role in the production of melanin or have antioxidant properties that prevent the degradation of melanocyte cells and keep them healthy and functioning properly.

Vitamins B12 and D3 are essential for cell metabolism and DNA repair, which are both necessary for maintaining the functionality of melanocytes and preventing their degradation. Copper aids in the production and transportation of melanin in our body as it activates tyrosinase, an enzyme that converts the amino acid tyrosine into melanin. Lastly, calcium, along with other minerals like iron and zinc, also plays an essential role in intracellular signaling and enzyme activity that impact the production and function of melanin.

So, introducing these nutrients to our bodies through consuming foods that contain them may be an important yet often overlooked factor in influencing specific changes in our appearance in a world obsessed with addressing the symptoms rather than the potential causes of a particular concern.

Some fantastic sources of these nutrients are leafy greens like spinach, kale, and Swiss chard, salmon, oysters, eggs, chicken, and beef liver.

Targeted supplementation with vitamins B12 and D3, zinc, iron, and copper may help address deficiencies.

In addition to incorporating nutrient-dense foods into our diet, specific supplements may be an effective and convenient way to ensure we get the necessary nutrients to maintain full, healthy, and vibrant hair. Targeted supplementation with vitamins B12 and D3, zinc, iron, and copper may help address deficiencies and maintain your hair's natural color for longer.

Additionally, beef liver capsules, in particular, which have become popular on platforms such as X and TikTok, where many boast about positive changes in their appearance and energy levels since incorporating this supplement into their daily routines, may also be worth considering as an easy way to get the necessary nutrients for preventing graying hair and improving the quality of day to day life.

That said, while more research is certainly needed to determine the effectiveness of specific supplements in preventing graying hair, one thing is for sure: A balanced diet rich in essential nutrients can go a long way in maintaining our overall health and appearance.

How Much Gray Is Just Right?

While many of us can become discouraged or go into a full-on panic mode upon noticing our first gray hairs, the truth is, there's no need to do so. In fact, graying hair is just as normal as any other sign of aging and shouldn't cause us to feel like we're losing our value.

On average, gray hairs start to appear in our 30s, with gray hairs in mid-twenties being considered premature but nevertheless common in many individuals. Now, while we can make an effort to lead healthier lives, this doesn't remove the possibility that many healthy young people have experienced their first grays in their mid or even early twenties.

The beginning phase, often called the "salt and pepper stage," is when most people notice a few scattered gray strands. From there, the percentage of gray hairs increases by about 10-20% each decade.

However, let's not forget that diet and lifestyle, although important, are just parts of the equation, and for many, genetics may play an essential role in the activity of catalase, the production of melanin, and how we age in general.

Some genes, such as a specific variant of the IRF4 gene, have previously been associated with premature graying, particularly in people of European descent. This gene is involved in regulating the production and storage of melanin in hair follicles, and certain variations may result in decreased melanin production and storage, leading to earlier graying.

Closing Thoughts

Graying hair can be the result of many internal and external factors. However, be it genetics or our lifestyle habits catching up with us and suggesting that perhaps it's time to start paying more attention to what we put into our bodies rather than what we put on them, it's also important to remember that gray hair is not something we should fear or desperately try to hide.

At the end of the day, the one factor we can't affect will eventually catch up with all of us; however, taking the best care of your health and body through proper nutrition and self-care is always a good idea, regardless of whether it will keep your hair's natural color or not.

So, instead of stressing about how much gray is too much, let's strive to age gracefully, with confidence and acceptance, knowing that our gray hairs are just a small part of who we are and that the wonderful experiences that have brought us to this point in our lives are what truly matter.
