Why Hair Turns Grey and What Affects It

If you’ve ever wondered why hair turns grey even before getting older, you’re not alone. For many social media users, content creators, and professionals who are always in front of the camera or public eye, hair color is more than just appearance—it’s part of their personal brand. That’s why understanding the reasons behind this natural change, and what influences it, is important. Whether it’s genetics, lifestyle, or stress, knowing why grey hair helps people take better care of their hair and embrace the changes with confidence.

Overview of Key Ideas in the Article

Hair turning grey is a natural part of aging, but it’s not always dependent on age alone. There are genetic, emotional, and physical factors that affect melanin production—the pigment that gives hair its color. In this article, we will discuss the main reasons why hair changes color, from biological processes to the effects of lifestyle, stress, and nutrition. There are also tips on how to care for hair once it starts to change color.

How Hair Gets Its Color Grey

The color of our hair results from a pigment called melanin, produced by cells found in hair follicles. Two types of melanin are responsible for color: eumelanin, which gives black or brown tones, and pheomelanin, which gives yellow or red hues. The combination of these two creates different hair shades—from jet black to strawberry blonde.

With each new strand that grows, melanocyte cells actively produce melanin. However, as we age, the activity of these cells weakens until they stop producing pigment altogether. That’s when new hair begins to appear in a different color other than black.

Why Hair Turns Grey as We Age

One of the most common answers is age. It is normal for many people to start having grey hair between the ages of 30 and 40. Over time, melanin production in the body decreases. The follicles that once actively made pigment become tired and stop functioning.

Sometimes, hair doesn’t change color all at once. Some strands may already be grey while others still retain color. This is natural because pigment-producing cells degrade at different rates.

Reasons Why Hair Turns Grey (Besides Age)

Here are some reasons why hair may turn grey even if you are not yet at the usual age expected for it. Besides natural aging, there are internal and external factors that can affect your hair color.

Genetics

Hair whitening is often inherited. If your parents or grandparents turned white early, it’s likely the same will happen to you. Some people have white strands as early as age 20, while others retain naturally dark hair until age 50. Different ethnicities also have different timing of greying—people of European descent tend to grey earlier compared to those of Asian or African descent.

Stress

Although long debated whether stress is directly linked to hair turning grey, some studies show a connection between chronic stress and hair pigmentation. One well-known experiment was done on mice, showing that stress hormones affected melanocyte stem cells. This doesn’t mean a single day of stress will make your hair grey, but ongoing mental and physical pressure can cause biological changes.

Nutritional Deficiency

The body needs adequate nutrition to keep hair healthy. Vitamin B12, iron, copper, and folic acid are among the nutrients related to pigmentation. When the body lacks these, melanin production may weaken. For example, some vegetarians or people with anemia experience faster hair turning grey.

Smoking and Lifestyle Choices

According to a study, smokers have a higher chance of early hair changing color compared to non-smokers. This is due to oxidative stress caused by free radicals from cigarettes. Additionally, lack of sleep, excessive alcohol intake, and lack of regular exercise may contribute to early grey strands.

Illness and Medical Conditions

Some conditions directly affect hair pigment. Vitiligo, an autoimmune disorder, causes loss of melanin not only on the skin but also on hair. Thyroid problems like hypothyroidism or hyperthyroidism also affect hair health. In such cases, it’s best to consult a doctor for proper diagnosis.

When Is Hair Turns Grey Considered Normal or Abnormal?

If hair becomes grey before age 20 (for Asians), there may be other reasons aside from age. But if it is gradual and consistent, it is likely just part of natural aging. If accompanied by other symptoms like thinning, hair loss, or changes in texture, there may be a deeper health issue. It’s advisable to see a dermatologist or doctor if you have concerns.

Is There a Way to Prevent or Delay Hair Turning Grey?

Here are some possible ways to delay hair color changing, according to expert observations and many people’s experiences. Although not guaranteed solutions, these steps may help keep your natural hair color longer.

Nutrition: Foods for Hair Color

There’s no sure way to stop hair turning grey, but some things might help slow it down. Having a balanced diet is one of the main steps. Make it a habit to eat foods rich in B-vitamins, protein, and antioxidants.

Supplements: Modern But Limited

Some supplements marketed for hair pigmentation exist, but not all have enough scientific backing. It’s better to consult a specialist before using such products.

Hair Care Products

“Anti-grey” shampoos or treatments are becoming popular. Some contain ingredients like copper peptides or catalase, which are said to help slow the process of becoming grey. However, effects vary from person to person.

Beliefs: Myth or Truth?

There are many beliefs about greying, such as “if you pluck one grey hair, more will grow.” There’s no evidence supporting this, so don’t easily believe rumors.

How to Care for Hair That Is Starting to Turn Grey

When you notice more grey hairs appearing, it’s important to change your hair care routine. Grey strands have different needs compared to natural black or brown hair, so it’s wise to be more careful in choosing products and treatments.

Moisture and Protection for Delicate Strands

Grey hair strands tend to be drier and thinner than pigmented hair. It’s best to use shampoos and conditioners with moisturizing ingredients like argan oil or shea butter.

Products for Grey and Silver Hair

There are products made for grey or silver hair, like purple shampoos that help prevent yellowing. For styling, light waxes or serums can make grey strands look shiny and healthy.

Embrace or Cover? It’s Up to You

You don’t have to cover grey hair immediately. Many people today proudly wear their silver strands as part of their style. But if you want to cover it, there are gentle hair dyes without ammonia or harsh chemicals.

The Impact of Hair Turning Grey on Mindset and Society

Hair becoming grey affects not just the physical aspect. In our culture, it’s often associated with aging, lack of self-care, or stress. That’s why some quickly buy dye to hide it. For people working in media, fashion, or beauty industries, there is sometimes pressure to maintain a youthful look.

On the other hand, society’s perspective is gradually changing. More people now recognize grey hair as a sign of experience and natural beauty. Being confident with grey hair can boost self-image more than hiding it every day.

What We Can Learn from the Process of Hair Becoming Grey

Grey hair is a normal and natural part of life. We may not control when it happens, but we can care for our hair to keep it healthy and beautiful. Understanding why hair turns grey not only helps with hair care routines but also gives deeper respect for the natural changes in our bodies. While we cannot stop time, we can choose how to face it—with knowledge, confidence, and care.
