These cells are solely responsible for providing your hair with its right pigment. While the exact reasons remain unclear on how the melanocytes reduce its performance, it can cause the hair to lose the pigment and turn white. It is observed that people who are aging show reduced performance of melanocytes. People who are above forty years display reduced functioning of melanocytes. So, people who reach their forties can see their hair turning gray. As they reach 50 or 60 years, melanocytes stop functioning. When the melanocytes stop its function, then you can see the hair turning white. It is due to the lack of melanin.

In people with piebaldism, the cells determining the hair, skin, and eye color remains absent in certain areas. The cells determining the color is also known as melanocytes.

Waardenburg’s syndrome

Waardenburg’s syndrome

The tumor can develop in the brain, skin, eyes, kidneys, lungs, or heart. The growths developed are mostly benign (non-cancerous). A child with the condition exhibits the symptoms during birth others develop the symptoms over time.

Vogt- Koyanagi- Harada (VKH) syndrome

VKH syndrome refers to the disease caused due to the inflammation of melanocytes. Due to the inflammation, you can see changes in melanin, which produces the pigmentation. The disease can affect several body parts like ears, eyes, skin, and nervous system.

Giant congenital nevus

It refers to the genetic skin condition, causing a noncancerous skin patch that is abnormally dark due to the presence of melanocytes, the pigment-producing cells. It is observed that people suffering from genetic disease suffer from poliosis.

Alezzandrini syndrome

It is a rare syndrome with specific characteristics. People develop it due to the breakdown as well as the loss of cells present in the retina (also known as retinitis pigmentosa). The retina is present at the back of your eye and is sensitive to light. Apart from that, you can also see vitiligo (white patches on your skin), whitening of eyelashes and eyebrows, and poliosis. All these distinctive features appear on the same side of the face.

Autoimmune Diseases Causing White Hair Patches

When you suffer from any autoimmune disease, then you can develop poliosis. Autoimmune disease refers to the medical condition causing the immune system to attack your body cells. In normal cases, the immune system acts as a defense system in guarding your body against viruses, bacteria, and other harmful pathogens. When foreign invaders attack your body, the brain sends signals to send out an army of white blood cells to attack them. Due to disorder in your immune system, the white blood cells attack the cells in the body. The autoimmune condition triggering the problem are:

  • Vitiligo
  • Hypogonadism
  • Hypopituitarism

Acquired Poliosis

It means you develop the changes in your hair color as a result of various underlying medical conditions or due to the after-effects of taking some medication. So, it is not a genetic or congenital condition and you acquire it due to some issues in the latter part of your life.

Complications Of White Hair Patches

Poliosis is not a harmful condition in itself. So, if you see white hair patches without any other signs in your body, you never have to panic. The harmless condition occurs due to the lack of pigment in your hair follicles. This results in your dark hair becoming white or gray. You can suffer from the problem by birth due to some genetic predisposition or can appear at a later stage in your life without any warning. While the condition itself causes you no harm, you need to maintain caution as it may appear due to some underlying health issues. So, you need to consult a doctor. Here are some of the complications you can face due to poliosis:

Escalation Of Medical Condition

Medical issues can trigger poliosis. So, based on the underlying issue, the complication varies. Let’s see them in detail:



Melanoma is a dangerous type of skin cancer. Since it involves melanocytes, you can develop poliosis due to the condition. Melanocytes are the cells responsible for providing color for your skin and hair. Due to the depletion of melanocytes, it can result in hair going gray. So, if you see the condition, then get it diagnosed by the doctor. It is because melanoma is the most aggressive type of cancer as it causes dangerous results when it spreads. So, early identification of the lesion and better treatment can offer a good outlook.

Thyroid Disorders

You need to see a doctor for getting proper treatment for thyroid disorders. Without proper treatment, you need to face complications. So, without medical intervention, you can experience changes in a heartbeat (dangerous low or fast heartbeat), the low healing power of injuries, and severe pain.

Inflammatory Conditions

Inflammatory condition like autoimmune problems occurs when your immune system starts attacking the tissues in the body. Due to the condition, the immune system considers your body’s cells as foreign invaders and attacks it. It can cause inflammation, which can also result in turning the hair gray.

Lack Of Self Esteem

In some cases, the condition is triggered by psychological stress and medications. With proper medical intervention, you can overcome the condition. But, the patches of white strands can make you feel self-conscious. Most people like to have an attractive visual appeal to make an impression. With gray strands, your confidence levels plummet. To regain your self-confidence, you need to undergo treatment to reverse poliosis or dye your strands.

Most people try to ignore the condition by thinking it as harmless or the time, effort, and money it takes for the treatment. But, some people suffer from underlying health conditions that can result in serious complications without medical intervention. So, you need to see a doctor to eliminate the presence of any underlying health condition. With proper treatment and management, you can overcome the distress and mental issues the condition can trigger.

Diagnosis Of White Hair Patches

Poliosis can occur due to various reasons. So, you need to see a doctor to detect the underlying cause triggering the condition. Some serious health conditions can lead to the problem. So, finding the exact cause of the problem is essential to determine the treatment. Here are the methods to diagnose the problem:

Thorough Physical Checkup

It helps understand if an underlying health issue or medication results in the condition. Based on the assessment, your doctor suggests further tests.

Blood Test To Detect Reason For White Hair Patches

In some cases, poliosis occurs due to vitamin deficiencies, thyroid disorders, or other serious conditions. So, you need to provide a sample of your blood for testing. The blood test can help uncover the medical condition triggering the condition.

Nutrition Study

Nutrition Surveys are usually national cross-sectional studies that are performed to assess the nutritional status of a selected population, identify the group at risk of chronic malnutrition, evaluate existing nutritional problems, and inform evidence-based nutrition policies

 Neurological Tests

Since certain neurological disorders like Vogt-Koyanagi-Harada disease, tuberous sclerosis, trigeminal neuralgia, and neurofibroma can cause poliosis, your doctor suggests some neurological tests to detect the issue.

Skin Sample Analysis

As suggested earlier, skin cancer can result in poliosis. So, your doctor suggests a skin analysis, which detects the presence of cancerous cells that trigger the condition.

Based on the diagnosis, your doctor determines the treatment needed to deal with the condition. The condition is not a disease itself. So, people who suffer from poliosis alone are healthy. They just see the gray hair, which can occur due to hereditary or other medical condition.

Treatment For White Hair Patches

While there is no proper treatment to permanently change the gray or white hair, triggered due to poliosis. But, you have a combination of treatment options to reverse the condition to an extent. It is important to uncover the underlying condition triggering the problem for effective results. The treatment options available are:

Eliminate Causative Factors

Combination Of Therapies

Studies have confirmed the efficiency of the combination of treatment can help reverse poliosis. So, people who can wait for patients to see the effects of the condition along with vitiligo reversed can try it. It involves undergoing a skin grafting treatment. You need to undergo epidermal grafting on the affected region. So, the doctor targets the depigmented skin beneath your gray hair. Then, you need to undergo laser therapy sessions. Your doctor uses a UV-B lamp ray on the affected area repeatedly. Along with the therapy you need to take oral medication and apply Ammi majus (herbal medication) available in lotion/ointment form on the affected area. You have to undergo therapy for several months. It may take several sessions to see the color returning to the area. If you want the condition to reverse, you need to make your mind to undergo intensive therapy. It is also time-consuming and expensive.

Dye Your Hair For Covering White Hair Patches

You can cover the white hair patches by opting for hair coloring. Hair dye or hair color is the simplest and highly-effective procedure to color the gray patches. It is neither expensive nor time-consuming as you can try it at home. While coloring your hair at a saloon offers more professional results, during the COVID-19 pandemic, you fear for your safety. So, you can try hair coloring at home by buying the best shade at the store. You can choose the color that looks close to the current strand’s color. Look at the boxes as they have displayed color. You can hold the box next to your locks to find the perfect shade.

To maintain the effectiveness of the color, you need to limit using water on your hair. It is because the salt, chlorine, and minerals in water can result in the hair’s cuticle to lift. It results in pigment loss. Use dry shampoo and limit the wetting of hair for maintaining the color applied. You can use a home kit to complete the process at home. But, you will have to re-dye the strands when the lighter roots make its appearance.

Use Head Cover

If you are not keen on using hair color, then you can choose to wear a head cover. So, you can opt for bandanas, hats, headbands, or other hair coverings available.
