Understanding Melanin Production in Hair
Jun 04, 2025 | By Edss Tolentino

Ever wondered why our hair changes color as we age? It all comes down to melanin, the natural pigment responsible for giving our hair its rich color. As we grow older, melanin production in hair gradually slows down, leading to the appearance of gray or white strands. This process has sparked growing interest among many people looking to prevent or even reverse graying. With more focus now on natural solutions and science-backed methods, understanding how melanin works in hair pigmentation is becoming more important than ever.
Understanding Melanin and Color
To truly understand how our hair gets its color, and why it changes over time, we need to dive into the science of melanin and hair pigmentation. Hair color is determined by melanin, a pigment produced by specialized cells called melanocytes in hair follicles. These cells play a key role in the hair growth cycle, especially during the anagen (growth) phase, when melanin is produced and infused into the hair strand. There are two primary melanin types in hair: eumelanin (which gives black or brown shades) and pheomelanin (responsible for red or yellow hues). The enzyme tyrosinase is essential in this process, as it drives melanin synthesis. Over time, due to aging or environmental factors, melanocyte activity decreases, leading to melanin loss and gray hair.
This connection between melanin and hair aging has fueled interest in how to increase melanin in hair naturally or through melanin supplements for hair. As a result, many are now exploring anti-grey hair treatments that target melanocyte health and melanin production to preserve or restore youthful hair color.
Melanin Production in Hair: Melanogenesis Process
Have you ever wondered exactly how melanin is produced in hair? The secret lies in a fascinating biological process called melanogenesis - the production of melanin in the body. It all starts in the melanocytes in hair follicles, where melanin is created and transferred to the hair shaft during the growth phase. Melanin is the pigment responsible for melanin and hair color, with two main melanin types in hair: eumelanin, which gives hair black or brown shades, and pheomelanin, which adds red or yellow tones. The balance of these pigments is what gives each person their unique hair color.
At the heart of melanin production is an enzyme called tyrosinase, which kicks off the process by converting the amino acid tyrosine into melanin. But tyrosinase doesn’t work alone, it relies on the presence of copper and other amino acids to function efficiently. If this enzyme is lacking or becomes less active, melanin production slows down, resulting in melanin loss and gray hair.
This is where the link between melanin and hair aging becomes crucial. As we age, melanocytes can become damaged or reduce their activity, leading to less pigment being produced and more gray or white strands. It’s no surprise that many people are looking for ways to increase melanin in hair naturally, whether through diet, lifestyle, or the use of melanin supplements for hair.
What Affects Your Hair Color?
The answer lies in the complex world of melanogenesis. It is the biological process responsible for producing melanin, the pigment that gives your hair its color. But melanin production isn't just about biology; it's influenced by a mix of genetics, aging, and lifestyle choices. Let’s break it down in a fun and informative way.
Genetic Blueprint
Your DNA plays a major role in determining your natural hair color and how it may change over time. Specific genes influence the type and amount of melanin your body produces:
- MC1R gene: This gene helps control whether your hair has more eumelanin (dark brown/black pigment) or pheomelanin (red/yellow pigment). Variations in MC1R are often linked to red hair and increased sensitivity to UV rays.
- IRF4 gene: IRF4 influences melanin biosynthesis by regulating the expression of genes involved in pigment production. It also plays a part in how your hair color changes with age.
- Genetic makeup also affects how efficiently tyrosine (an amino acid essential to melanin production) is converted into melanin during melanogenesis.
Aging
As we get older, it’s completely natural for melanin levels in hair to drop. Here’s how aging plays a role:
- Melanocyte stem cells, which are responsible for replenishing melanocytes in hair follicles, gradually decline over time.
- Fewer melanocytes mean less pigment being deposited during the hair follicle pigmentation process, leading to graying.
- This age-related decrease in melanin is one of the most common causes of hair color change.
Lifestyle and Environmental Factors
Your environment and daily habits can also impact the color and vibrancy of your hair. Here’s how:
- Oxidative stress and hair color: Exposure to free radicals from pollution, smoking, and UV radiation can damage melanocytes, disrupting melanin production.
- Poor nutrition: A diet lacking in essential nutrients like copper, iron, or vitamins B12 and D can impair melanin biosynthesis and reduce pigment formation.
- Stress and lack of sleep may also indirectly affect how well your body maintains healthy melanocytes and pigment levels.
Natural Ways to Preserve Melanin in Hair
As people become more conscious of healthy aging, the interest in understanding how melanin is produced in hair and how to naturally maintain it is on the rise. The good news? There are practical, natural ways that may help increase melanin in hair naturally and slow down signs of graying.
Feed Your Follicles
What you eat plays a huge role in maintaining healthy melanocytes in hair follicles, the cells responsible for producing melanin.
- Tyrosine-rich foods: This amino acid is essential for tyrosinase and melanin synthesis. Load up on foods like almonds, avocados, eggs, and soy.
- Antioxidant-rich fruits and vegetables: Blueberries, spinach, and sweet potatoes help fight free radicals that cause melanin loss and gray hair.
- Copper-containing foods: Copper helps activate tyrosinase. Incorporate nuts, seeds, lentils, and dark chocolate into your meals.
Boost from the Inside
If your diet isn’t giving you all the nutrients needed for melanin production, supplements can fill in the gaps:
- B-complex vitamins: Especially B12 and B6, which support melanin and hair aging by maintaining nerve and follicle health.
- Copper supplements: Aid in the melanin biosynthesis process and support the activity of tyrosinase.
- Catalase: An enzyme that breaks down hydrogen peroxide, which can bleach hair from the inside out and accelerate melanin loss and gray hair.
- Consider high-quality melanin supplements for hair that are specially formulated to target pigmentation issues.
Targeted Action on the Scalp
While nutrition works from the inside, topical solutions deliver direct results to the scalp and follicles.
- Mayraki Anti-Grey Hair Color Restoring Treatment is one of the leading anti-grey hair treatments available today. It’s formulated to help reactivate melanocytes in hair follicles and stimulate melanin types in hair (eumelanin and pheomelanin) without using harsh dyes or chemicals.
- This innovative product supports tyrosinase and melanin synthesis using plant-based ingredients and peptides that nourish the scalp and restore hair’s natural color.
- Users report visible improvements in color retention and a reduction in gray strands with consistent use.
Wrap-Up
Understanding the science behind melanin production in hair gives us valuable insight into why our hair changes color over time and what we can do to slow that process down. From the role of melanocytes and tyrosinase to the impact of aging and lifestyle factors, it’s clear that supporting your body naturally can make a difference. By taking proactive steps like nourishing your body with the right nutrients, using targeted supplements, and exploring effective topical solutions you can help preserve your hair’s natural pigment. If you're ready to take control of your hair’s future, Mayraki’s natural anti-grey solutions offer a gentle, science-backed way to support and restore healthy melanin levels in your hair.
