As people age, it is typical for their hair color to turn grey. Recently, I have seen that people are beginning to age more quickly than they normally would—as early as in their 20s. Premature greying of hair is now extremely common.

Today’s youth are more inclined to have grey or silver hair, which is an early symptom of ageing hair. There is an increase in the age group of people who embrace early or premature greying of hair due to a variety of factors.

Millions of hair follicles or tiny sacs line the skin of the human body. The follicles generate pigment cells that contain melanin and form hair. The gradual loss of pigment-producing cells in hair follicles over time results in white hair. In this post, we will see 9 typical causes of premature greying of hair.


Even if the fundamental causes of early greying have not been fully uncovered, genetics is one of the main contributing factors. The abnormalities in the cells that produce melanin or the failure to produce melanin at a young age are both caused by genetic factors.

Genes cannot be altered. You can always dye your hair, though, if you do not like the way your grey hair appears.

2. Stress

Premature greying of hair is more likely to occur if you encounter persistent stress for a long time. Stress will cause your hair to become grey considerably more quickly, regardless of how hectic your family life is, how worn out and stressed you are, etc. Stress has been associated with a reduction in stem cells in hair follicles; hence, if you constantly feel guilty about yourself, you are more likely to get white hair.

3. Lack of vitamins and minerals

Premature greying of hair has been linked to inadequate levels of vitamins and minerals. Iron, folate, vitamin D, and vitamin B12 deficiencies are other factors that might contribute to follicle whitening. Low levels of biotin and a folic acid deficiency are also linked to premature greying of hair.

4. Unhealthy eating

A diet that is out of balance might hasten the ageing of your hair. Free radical generation in the body, which can cause hair to become grey, is more likely to occur in those who consume processed meals, cold beverages, and a lot of salt and sugar. To avoid greying and maintain the health of your hair, make sure you eat a nutritious diet.

5. Thyroid condition

Premature greying of hair may also result from hormonal changes brought on by thyroid issues, such as hyperthyroidism or hypothyroidism. At the base of your neck, there lies a butterfly-shaped gland called the thyroid. It aids in maintaining various biological processes, including metabolism. The condition of your thyroid may also have an effect on the color of your hair. An overactive or underactive thyroid may also cause your body to produce less melanin.

6. Smoking

Smoking is not only bad for your health, but it can also ruin your hair. It causes blood vessels to enlarge, which decreases the blood supply to your hair follicles. When cigarette smoke is inhaled, its chemicals can harm hair follicles and hasten the occurrence of grey hair.

7. Immune disorder

An autoimmune disorder may potentially be the cause of premature white hair. The immune system of the body attacks its own cells during this time. It may assault the hair in conditions like alopecia and vitiligo, which result in pigment loss.

8. Oxidative strain

Oxidative stress is a potential contributor to white hair. Free radicals overtake antioxidants in this situation. In order to combat free radicals, antioxidants are crucial, but if there are not enough of them, they can cause premature ageing and a host of other health problems. Excessive oxidation is a disorder known as vitiligo. In turn, this causes the premature greying of hair by destroying hair follicles.

9. Chemical-filled hair products

Shampoos and conditioners, which include compounds that inhibit the formation of melanin, can speed up the occurrence of grey hair in people. If used frequently, bleaching chemicals like hydrogen peroxide included in hair colors can also turn hair white.
