Poliosis or White Streak in the Hair

Poliosis is the medical term for a naturally occurring tuft of white hair. Some people are born with white streaks in their hair, which can be mistaken for normal birthmarks. In this condition, melanin or melanocytes are reduced or nonexistent in the hair bulbs of the afflicted hair follicles.

While this white patch is most commonly seen on the forehead, poliosis can affect the brows, eyelashes, or hair on any part of the body. It can happen at any time in one’s life. Poliosis is not a dreadful medical condition. Most people with poliosis are healthy and only have it because their hair and skin lack color in that location. It can be inherited and also occur as a result of unusual medical disorders.

Conditions associated with poliosis


Several conditions are associated with poliosis. They could be a result of the white streaks, the causes of the streaks, or just easily associated with poliosis by appearance and shared symptoms.

Conditions that have nothing to do with poliosis:

Examples of such conditions include:

Hair heterochromia

This condition is defined as the existence of two naturally occurring distinct hair colors in a single individual. Even though head and facial hairs are frequently different colors among fair-haired people, hair on the other parts of the body is significantly darker than scalp hair. For the most part, eyelashes are darker in color than scalp hair. Furthermore, in a normal scalp, an observer can detect a minor difference in the color of each hair shaft. The news recently reported a kid with a circular area of localized head hair heterochromia with no underlying problems.


Is commonly referred to as oculocutaneous albinism (OCA), a set of genetic illnesses in which there is little or no synthesis of the pigment melanin. The color of the skin, hair, and eyes is determined by the type and quantity of melanin produced by the body. Because melanin is involved in the formation of optic nerves, people with albinism experience visual issues.

Albinism is commonly visible in the skin, hair, and eye color; however, changes can be subtle. Individuals with albinism are more vulnerable to the harmful effects of the sun, putting them at a higher risk of acquiring skin cancer.

Although there is no remedy for albinism, people with it can take precautions to preserve their eyes and skin and improve their vision.


This is a condition that results in patches of the skin losing color. When pigment-producing cells pass away or stop working, vitiligo develops. Any area of the body, such as the mouth, hair, and eyes, might experience skin color loss. People of darker skin tones could detect it more readily. Although the condition is not cured by treatment, the skin may look better. While researchers are working on a solution, there is no medicine that can cure this disease. Although there are treatments that can help regain lost skin color, the effects may fade over time. Many individuals return for follow-up care to maintain their results.


This is the accumulation of small clusters of proinflammatory cells in various regions of the body. The most prevalent sites for growth are the lungs, lymphatic system, eyes, and skin. The symptoms differ depending on which organs are damaged. Sarcoidosis frequently resolves on its own. It can linger in some people for years and cause organ damage. In most cases, no therapy is required.

Conditions that have something to do with poliosis:

Waardenburg syndrome

Is a hereditary condition that can be detected at birth. Primary characteristics include significant facial defects, notably decreased hair, skin, or iris coloring in both eyes, and congenital deafness. A white lock of hair developing above the brow, premature whitening of the hair, changes in the hue of the two irises or different areas of the same iris (heterochromia irises), and depigmented skin regions are further examples of pigmentary anomalies. Because of the sideways shifting of the innermost angles of the eyes, some people with the condition may have an exceptionally broad nasal bridge.

Alezzandrini syndrome

Is a highly unusual illness marked by retinitis pigmentosa (the loss of cells within the retina—the light-sensitive tissue that covers the rear of the eye), whitish spots in the skin (vitiligo), and whitening of the eyebrows and lashes (poliosis) on the side of the facial area. Other indications and symptoms that have been described include hearing loss, a spot of white hair on the scalp, a café-au-lait patch on the neck, and vision loss, all of which are on the same aspect as the eye. The cause is currently unknown, but it may be connected to viral diseases or autoimmune processes. Eye exams, hearing tests, and treatment for vitiligo skin lesions are all part of medical care.

Vogt-Koyanagi-Harada disease

With no known etiology, this unusual ailment affects the skin, eyes, hearing, brain, and meninges, among other physiological systems. An abrupt loss of vision is the main sign. There may also be neurological symptoms like vertigo, headaches, and tiredness. Possible adverse effects include hearing loss, alopecia (hair loss), skin discoloration, and loss of pigment in the eyelashes and hair (poliosis).

Tuberous sclerosis

In patients having tuberous sclerosis complex (TSC), the cells do not stop dividing when they should. This condition implies that tumors can grow in various locations in your body. They are not malignant, but they could cause problems where they are growing. Some therapies can help to shrink the tumors while also improving your comfort. Every circumstance is different. TSC’s effects could vary depending on where in the body it appears. The tumors, which can develop in the lungs and cause breathing difficulties, might mimic thick or thin spots on the skin.


While poliosis is still defined by the presence of a white streak of hair on the head and other parts of the body, similar conditions may or may not be linked to it.

There are also situations where people whiten their hair color for cosmetic purposes, sometimes bleaching the whole hair or doing it in patches and streaks to achieve the desired look.
