Understanding Grey Hair
Grey hair is a natural part of the aging process, but what causes this change in hair color, and why does the texture and structure of hair alter when it turns grey? Let’s dive deeper into the science behind grey hair.
What Causes Hair to Grey
Hair graying is a common age-associated feature occurring to varying degrees in all individuals. This process is attributed to the loss of pigment-forming melanocytes from the aging hair follicle, which leads to fewer melanosomes being incorporated into the hair shaft. Alongside this, there’s also a defect in melanosome transfer to the cortical keratinocytes, which further contributes to the reduction of melanin synthesis. A decrease in melanin synthesis is associated with a decrease in tyrosinase activity (Source).
Experimental evidence supports the hypothesis that oxidative stress plays a significant role in the aging process, including the aging of hair. With age, the production of free radicals increases, while the endogenous defense mechanisms decrease. This imbalance leads to progressive damage of cellular structures, resulting in the manifestations of aging in hair, such as graying and hair loss.
Texture and Structure of Grey Hair
The texture and structure of grey hair differ from pigmented hair. Grey hair is often coarser and less manageable, making it more challenging to hold a temporary or permanent set and more resistant to incorporating artificial color. Grey hair has increased sensitivity to weathering, increased cysteic acid residues, and decreased cystine. It also shows increased fiber reactivity to reducing and oxidizing agents.
Inflammatory phenomena and fibrosis also play a role in the pathogenesis of androgenetic alopecia (AGA), a form of hair loss that affects a significant proportion of individuals, particularly men. Microscopic follicular inflammation occurs in regions of actively progressing alopecia, associated with perifollicular fibrosis. This inflammation around the individual hair follicle could be due to microbial colonization of the follicular infundibulum or the response of keratinocytes to oxidative stress. This inflammation leads to connective tissue remodeling and perifollicular fibrosis (Source).
Understanding the causes and characteristics of grey hair is the first step in managing the changes that come with it, including the yellowing of grey hair, which we will explore in the next section.
Factors Causing Yellowing in Grey Hair
You may find it puzzling when grey hair starts to develop a yellowish tint. This is a common problem, and understanding what causes grey hair to turn yellow can help you prevent and treat this issue effectively.
Environmental Pollutants and Yellowing
Grey hair is particularly susceptible to environmental pollutants, which can cause a yellow tinge. For example, smoke from cigarettes and other sources can cling to the hair shaft and cause discoloration. Similarly, pollution in the air can also lead to yellowing of grey hair (Healthline).
Furthermore, if you love swimming, you should be aware that chlorine in swimming pools is another common culprit. It can react with your hair, causing it to take on a yellow hue (Healthline).
Role of Lifestyle Habits
Aside from environmental pollutants, lifestyle habits also play a significant role in yellowing of grey hair. Overexposure to the sun, for instance, can damage the hair shaft and lead to yellowing. Regular use of heat styling tools such as flat irons and curling irons can also contribute to this issue by causing hair damage and discoloration.
As a professional or a consumer, understanding these lifestyle factors can help you make informed decisions about your hair care routine, and protect your grey hair from turning yellow.
Impact of Hair Products and Tools
Certain hair products can also contribute to the yellowing of grey hair. Overuse of styling products and hair oils can lead to product buildup, which can cause your grey hair to appear yellow over time (Manhattan Grey).
Moreover, hair color and bleaching agents can react with the hair shaft differently when applied to grey hair, which can also result in a yellow hue. This calls for careful selection and use of hair products if you have grey hair.
In summary, a combination of environmental factors, lifestyle habits, and hair products and tools can cause grey hair to turn yellow. By understanding these factors, you can adopt the right strategies and products to prevent and reverse yellowing in grey hair.
Nutritional Deficiencies and Yellowing
Your overall health, including your diet and nutritional intake, plays a significant role in the health and appearance of your hair. This is particularly true for grey hair, which can be more susceptible to discoloration due to nutritional deficiencies or imbalances.
Vitamin B12 and Grey Hair
Vitamin deficiencies, particularly vitamin B12, can contribute to the yellowing of grey hair. Vitamin B12 plays an essential role in your body’s production of melanin, the pigment that gives hair its color.
When your body is deficient in this vitamin, it can affect the health and color of your hair. In the case of grey hair, a lack of adequate B12 can lead to a yellowish discoloration.
If you’re experiencing yellowing in your grey hair, it could be beneficial to have your B12 levels checked. A simple blood test can determine if you have a deficiency. If this is the case, incorporating more B12-rich foods into your diet, such as fish, poultry, eggs, and dairy, or taking a B12 supplement, could help improve the health and appearance of your hair.
Impact of Diet on Hair Health
Diet plays a crucial role in maintaining the health and vibrancy of your hair. A well-rounded diet rich in essential vitamins and minerals can help to prevent the yellowing of grey hair.
On the other hand, a diet lacking in key nutrients can leave your hair more vulnerable to discoloration. This is because your hair requires certain nutrients to maintain its color and structure, and when these are lacking, it can lead to changes in hair color and texture, including yellowing.
In addition to B12, other nutrients that are important for maintaining hair health include:
- Vitamin A: This vitamin helps to produce sebum, which moisturizes the scalp and keeps hair healthy.
- B-vitamins: In addition to B12, other B-vitamins like biotin, are essential for hair health.
- Vitamin C: This powerful antioxidant helps protect hair follicles against damage from harmful molecules called free radicals.
- Vitamin D: Low levels of this vitamin have been linked to hair loss.
- Iron: This mineral helps red blood cells carry oxygen to your cells, including hair follicles.
By ensuring that your diet includes these essential nutrients, you can help to maintain the health and color of your grey hair and prevent yellowing. However, it’s important to remember that diet isn’t the only factor at play. Environmental pollutants, smoking, and hair care products can also contribute to the yellowing of grey hair. Therefore, it’s crucial to take a holistic approach to hair care to maintain the health and vibrancy of your grey hair.
Neutralizing Yellow Tones in Grey Hair
Once you understand what causes grey hair to turn yellow, you can take steps to neutralize these yellow tones. This can be achieved through the use of clarifying shampoos and toning treatments.
Use of Clarifying Shampoos
Clarifying shampoos are a potent weapon against yellowing in grey hair. They work by thoroughly cleaning the hair shaft and removing any build-up of minerals, pollutants, or hair products that may be contributing to the yellow tint in your grey hair.
As a professional, you should recommend your clients to use a clarifying shampoo once or twice a month to keep their grey hair looking bright and vibrant. However, caution them against overuse as clarifying shampoos can be quite drying. They should always follow a clarifying shampoo with a hydrating conditioner to keep their hair moisturized and healthy.
Role of Toning Treatments
Toning treatments, such as purple shampoos and conditioners, can also play a vital role in neutralizing yellow tones in grey hair. These products have a purple or blue tint which counteracts the yellow tones, keeping grey hair looking vibrant and true to color (Manhattan Grey).
Here’s a simple explanation: on the color wheel, purple and yellow are opposites. When you apply a purple-tinted product to yellow-tinted hair, it neutralizes the yellow and brings your hair back to a neutral, silver or grey tone.
Regular use of these toning treatments can prevent yellowing and maintain the natural silver or white tone of grey hair. Just like with clarifying shampoos, it’s important to follow up with a hydrating conditioner to prevent dryness and keep the hair healthy.
As a professional, you can recommend your clients to incorporate these treatments into their regular hair care routine. However, they should always follow the instructions on the product label and not leave these treatments on their hair for longer than recommended to avoid over-toning and ending up with purple or blue-tinted hair.
By understanding the factors that contribute to yellowing in grey hair and how to address them, you can provide your clients with the best advice and products to maintain the beauty and vitality of their grey hair.
