What Causes White Hair and how to prevent them?

Hair turns white as pigment cells lose melanin. Premature graying may stem from genetics or health factors
White hair, also known as “canities,” is a natural occurrence that many people experience as they age. It is a result of the gradual loss of pigment in the hair follicles, leading to a colorless or grey appearance. While white hair is a normal part of the aging process, it can occur at different stages and vary among individuals due to genetic, environmental, and lifestyle factors. Understanding that white hair is a natural and common phenomenon can help foster self-acceptance and appreciation for the unique beauty it brings.

Is White Hair Normal?

Yes, white hair is a normal part of the aging process for many individuals. As we age, our hair follicles gradually produce less melanin, the pigment that gives hair its color. This decrease in melanin production can lead to hair appearing grey or white.
White hair is a natural occurrence and is not considered a cause for concern. It is a normal variation in hair color that can happen at different stages of life for different individuals. While white hair is commonly associated with older age, some people may develop white or grey hair at a younger age due to genetic factors or other influences.
White hair can be a beautiful and unique feature that adds character and distinction to an individual’s appearance. Many people choose to embrace their white hair and view it as a symbol of wisdom, experience, and natural beauty. However, personal preferences may differ, and some individuals may choose to color their hair to achieve a different aesthetic. Ultimately, whether an individual embraces their white hair or chooses to color it is a personal choice. The most important thing is to feel comfortable and confident in one’s appearance, celebrating the natural changes that occur as part of the aging process.

What Causes Hair to Turn White?

Aging – The most common cause of white hair is the natural aging process. As we age, melanocytes, the cells responsible for producing melanin, gradually decrease in activity and may eventually stop functioning altogether. This leads to a lack of pigment in the hair, resulting in white or colorless strands.

Dr. Elizabeth Johnson, a hair biologist, states

“White hair is a natural consequence of the aging process and occurs when the pigment-producing cells in the hair follicles gradually cease functioning. While we can’t prevent white hair entirely, adopting a healthy lifestyle and taking good care of our hair can help support its overall health and delay the onset of white hair.”
Genetics – Genetic factors play a significant role in determining the timing and extent of white hair. Researchers have identified specific genes, such as the IRF4 gene, that are associated with early greying. If your parents or close relatives experienced premature greying, you may be more likely to develop white hair earlier in life.
Oxidative stress – Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body. Studies have suggested that oxidative stress may contribute to the greying of hair by damaging melanocytes and inhibiting melanin production. Factors such as exposure to environmental pollutants, smoking, and poor nutrition can increase oxidative stress levels.
Nutritional deficiencies – Vitamins B12, D, iron, copper, and zinc, play a role in maintaining hair pigmentation and if you are not getting them through your diet chances are more that you will have early grey or white hair.

Can you reverse white hair?
Reversing white hair is challenging, especially if they are genetically determined, as this often indicates a permanent change. However, if the cause is related to medical conditions or nutritional deficiencies, there may be a chance to slow down or halt the process, preventing further greying. Complete reversal may not be guaranteed, but proactive steps can still be taken to restore the natural pigment in your hair and potentially slow down the progression of premature greying.

How to Prevent Hair from Turning White?

Here are some measures that may help delay its onset or slow down premature hair whitening. These are the general remedies that could be followed by your own, but if you want an exact reason why it’s happening then consulting with a healthcare professional or dermatologist is advisable for personalized guidance based on individual circumstances.
Healthy Lifestyle – Maintaining a healthy lifestyle can promote overall hair health and potentially delay white hair. Regular exercise, a balanced diet rich in vitamins and minerals, and avoiding harmful habits like smoking can help reduce oxidative stress and support optimal hair pigmentation.
Stress Management – Chronic stress has been linked to premature greying. Engaging in stress management techniques such as meditation, exercise, and relaxation exercises can help reduce stress levels and potentially slow down the greying process.
Hair Care – Proper hair care can help maintain the health and vitality of your hair. Using gentle hair products, minimizing heat styling, and avoiding harsh chemicals can prevent damage to the hair follicles and promote healthy pigmentation.


In conclusion, white hair is a normal and natural part of the aging process. It occurs as the result of decreased melanin production in the hair follicles and can vary in timing and extent among individuals. Whether one develops white hair at an early age or later in life, it is important to recognize that it is normal to many and often not a cause for concern.
