Why does hair go grey and can supplements make a difference?






Unravelling the Mysteries Behind Why Hair Goes Grey.


Presented by Metulas Supplements.


Hair, the crowning glory of human beings, holds an intriguing mystery within its strands: the transformation from vibrant colours to shades of silver. While some embrace the silver fox aesthetic with grace, others may ponder over the science behind this natural phenomenon. The journey from pigmented to grey hair is a tale woven with biology, genetics, and a sprinkle of lifestyle factors.


Join us as we embark on a comprehensive exploration into the reasons why hair goes grey.


Understanding Hair Pigmentation:


Before delving into the greying process, let’s unravel the basics of hair pigmentation. The colour of our hair is primarily determined by two types of melanin: eumelanin, responsible for black and brown hues, and pheomelanin, contributing to red and yellow tones. These pigments are synthesized by melanocytes, specialized cells located in hair follicles. The interplay between genetics and environmental factors orchestrates the balance of melanin production, defining our hair colour.


The Greying Process:


Grey hair emerges when there is a decline in melanin production, leading to a loss of pigment. This transition typically occurs with age, as melanocyte activity diminishes over time. However, the precise mechanisms underlying this decline remain a subject of scientific inquiry.


  1. Genetic Predisposition: Genetics play a pivotal role in determining when and how our hair turns grey. Studies have identified several genes associated with premature greying, indicating a hereditary component to this process. Variations in genes such as IRF4, TYR, and BNC2 have been linked to the timing of greying, shedding light on the genetic factors influencing hair coloration.

  2. Oxidative Stress: Oxidative stress, resulting from an imbalance between free radicals and antioxidant defences, emerges as a significant contributor to hair greying. Reactive oxygen species (ROS) generated during metabolic processes can damage melanocytes, impairing their ability to produce melanin. External factors such as UV radiation, pollution, and smoking exacerbate oxidative stress, hastening the greying process.

  3. Decline in Melanocyte Stem Cells: The gradual depletion of melanocyte stem cells within hair follicles plays a crucial role in age-related greying. These stem cells replenish mature melanocytes, sustaining the production of melanin. However, with advancing age, the regenerative capacity of melanocyte stem cells diminishes, leading to a decline in melanocyte population and subsequent greying.

  4. Melanin Distribution: Beyond reduced melanin production, alterations in melanin distribution within the hair shaft contribute to the grey appearance. As melanocytes become less active, newly synthesized melanin may not evenly distribute along the hair strand, resulting in a mixture of pigmented and unpigmented areas.

  5. Hormonal Changes: Hormonal fluctuations, particularly during menopause in women and andropause in men, can influence hair pigmentation. Changes in hormonal levels, specifically a decline in oestrogen and testosterone, may impact melanocyte function, hastening the onset of grey hair.

The Role of Lifestyle Factors in Grey Hair:

While genetics lay the foundation for hair greying, lifestyle factors can exert a significant influence on the pace and intensity of this process.


  1. Diet and Nutrition: A balanced diet rich in vitamins, minerals, and antioxidants supports overall hair health and may help delay greying. Nutrients like vitamin E, B vitamins, copper, and zinc play essential roles in melanin production and antioxidant defence mechanisms.

  2. Stress: Chronic stress has been implicated in premature greying due to its effects on oxidative stress and hormonal balance. Elevated levels of stress hormones, such as cortisol, may disrupt melanocyte function, accelerating the greying process.

  3. Smoking: Smoking is not only detrimental to overall health but also detrimental to hair pigmentation. The toxins present in cigarette smoke induce oxidative stress, leading to premature greying and hair loss.

  4. Environmental Factors: Exposure to environmental aggressors, such as pollution and UV radiation, can expedite hair greying by increasing oxidative damage to melanocytes. Protective measures like wearing hats and using sunscreen for hair can help mitigate these effects.

What can you do about grey hair - if embracing it is not for you?

While the greying of hair is often perceived as a sign of aging, it also embodies wisdom, experience, and a journey well-lived. Embracing the natural evolution of hair colour can foster self-acceptance and redefine beauty standards. Whether one chooses to embrace their silver strands or explore options for colour restoration, understanding the science behind hair greying empowers individuals to make informed decisions about their hair care regimen.


Nourishing the Roots: Exploring the Benefits of Nutrients for Reducing Grey Hair.


The journey from vibrant pigmentation to silver strands is a natural part of aging, yet many seek ways to slow down or reverse this process. Beyond hair dyes and topical treatments, a growing body of research suggests that certain nutrients may play a role in maintaining hair colour and promoting overall hair health. Among these, amino acids like L-Arginine and L-Citrulline, collagen, vitamins C, D3, and K2, biotin, zinc, beetroot, as well as extracts such as resveratrol and grape seed extract, have garnered attention for their potential benefits in reducing grey hair. Whilst this is clearly a blatant promotional plug for our own product, Hair Therapy, we have been getting such great feedback from our customer with regards to the reversing of their grey hair that this blog was inspired! So we feel it would be remiss not to include Hair Therapy as we wouldn't want others to miss an opportunity to be aware of it! Let's delve into the science behind the nutrients contained in Hair Therapy and their mechanisms of action.


Amino Acids: L-Arginine and L-Citrulline:


Amino acids serve as the building blocks of proteins, including those essential for hair structure and pigmentation. L-Arginine and L-Citrulline are two amino acids known for their roles in promoting blood circulation and supporting nitric oxide production. Improved blood flow to the scalp can enhance nutrient delivery to hair follicles, potentially supporting melanocyte function and delaying the onset of grey hair.


Collagen:


Collagen, the most abundant protein in the body, contributes to the structural integrity of hair, skin, and nails. As we age, collagen production naturally declines, leading to various signs of aging, including hair greying. Supplementing with collagen may help maintain the strength and elasticity of hair strands, reducing breakage and preventing premature greying.


Vitamins C, D3, and K2:


Vitamins play crucial roles in maintaining overall health, and several have been linked to hair pigmentation. Vitamin C acts as a potent antioxidant, protecting hair follicles from oxidative stress and supporting collagen synthesis. Vitamin D3 regulates hair follicle cycling and may influence melanocyte activity, while vitamin K2 promotes calcium metabolism, which is essential for hair follicle function.


Biotin:


Biotin, also known as vitamin B7, is renowned for its role in promoting healthy hair, skin, and nails. While its direct impact on hair pigmentation is less understood, biotin deficiency has been associated with hair loss and premature greying. Supplementing with biotin may help maintain overall hair health and potentially slow down the greying process.


Zinc:


Zinc is an essential mineral involved in numerous physiological processes, including DNA synthesis and repair. Adequate zinc levels are critical for melanocyte function and melanin production. Zinc deficiency has been linked to premature greying, highlighting the importance of maintaining optimal zinc levels for healthy hair pigmentation.


Beetroot:


Beetroot is rich in antioxidants, vitamins, and minerals, including vitamin C, folate, and manganese. Its nitrate content may support nitric oxide production, improving blood flow to the scalp and nourishing hair follicles. Additionally, beetroot's vibrant red colour comes from betalains, compounds with potential antioxidant properties that may protect against oxidative damage to hair follicles.


Resveratrol & Grape Seed Extracts:


Resveratrol, a polyphenol found in grapes and red wine, has gained attention for its anti-aging properties and potential benefits for hair health. It exhibits antioxidant and anti-inflammatory effects, which may protect against oxidative stress-induced damage to hair follicles. Grape seed extract, similarly rich in antioxidants, may support hair growth and pigmentation by scavenging free radicals and promoting circulation to the scalp.


Incorporating Nutrients into Your Routine:


While these nutrients offer promising potential for reducing grey hair, it's essential to approach supplementation with caution and consult with a healthcare professional. A balanced diet rich in fruits, vegetables, lean proteins, and whole grains provides the foundation for healthy hair and overall well-being. However, for individuals seeking additional support, dietary supplements or topical treatments containing these nutrients may offer a complementary approach to promoting hair pigmentation and vitality.
