Grey hair is a normal part of aging. As we get older, we tend to develop strands or even a whole head full of grey hair. Unfortunately, not everyone is “old” when they start to sprout up grey strands. It can be difficult to wrap your head around what causes grey hair, but even more difficult to treat it appropriately. Below I am going to dive into the causes and the treatments you can do to prevent or slow down the process of greying hair on the head. Read on to learn more!

Grey Hair Facts (causes and treatments)

Did you know that your hair actually doesn’t turn the color grey? I bet this statement surprises a lot of you. According to science, as you age, the hair follicles produce less and less color. This color is known as melanin. As you get older, your hair is technically the same color as it was years ago, but the melanin production is much lower, causing the white or grey look to the hair strand. Hair strands will regrow a grey or white color on the scalp replacing old hairs that just went through the telogen phase of the hair growth cycle.

Have you ever heard that grey hair is more coarse than normal strands? Wrong! This statement is not true. Science has proven that the grey strands of hair on your head are actually more fragile and finer than other hairs. The grey hairs just feel this way to the touch because there is less oil produced in the hair follicle once hair starts growing in as a grey or white color.

One of the things we have to consider when we notice our hair becoming grey, is that more than likely, we also have a family member who has grey hair. Unfortunately, heredity plays a major role in why your hair may be beginning to grey. You can thank your mother, father, or even grandparents if you start to develop grey hair at a certain age.

What Causes Grey Hair?

what causes grey hair?

Grey hair can develop for many reasons such as diseases, illnesses, genetics, age and more.


Diseases such as autoimmune diseases can be major trigger points to developing grey hair. Alopecia is the most common autoimmune disease that can affect your hair. In many cases of alopecia and hair loss, the hair will actually regrow as a grey or white pigmented strand due to the lack of melanin.


Illnesses such as vitiligo can cause grey hair. Vitiligo is a condition where cells that are in charge of producing pigment are destroyed. This causes the skin tissues and the hair surrounding these tissues to turn white.


Genetics play a major role in individuals with grey hair. If you have parents or grandparents that developed grey hair at a certain age, chances are you will too.


Age is a main culprit to greying hair. Like mentioned above, as we age, our hair follicles are less able to produce the same melanin pigments as they once were. Although grey hair usually occurs in the midlife era of individuals, some people can start seeing grey hair as early as the age of 20. Likewise, some people never see grey hair in their lifetime.

Can Stress Cause Grey Hair?

Because our lives are constantly changing, grey hair can result from general stress as well as anxiety. The factors of stress and anxiety changes our hormone production, hair follicle function and our organ functions. Conditions that cause stress like pregnancy in women or a traumatic event can play a factor in what happens to your hair.

When your body responds to stress, it often damages healthy cells. Responses to stress can cause damage to your DNA, which later causes changes throughout your body. Stress can lead to a condition known as telogen effluvium which is responsible for causing your hair to shed up to three times quicker than normal. While it can’t cause you to become completely bald, it can cause the hair to grow back grey rather than your original hair color.

Try styling your hair differently. Male or female, try parting your hair a different way or on the opposite side to hide grey roots. Specifically, for females, slicked back buns are the most efficient way to hide those pesky grey roots.
