Poliosis on its own is not serious and does not cause other symptoms. Talk to a healthcare provider if you have poliosis and other symptoms or changes to your skin and hair. Sometimes poliosis is a sign of an underlying condition or reaction to medication that may require medical care. Vitiligo is a chronic autoimmune skin condition in which immune cells destroy melanocytes, the cells that produce pigments called melanin in your skin.

White hair from poliosis, though, won’t return to your natural color again. It’s caused by a lack of pigment and pigment cells, which leads to permanent color loss. Some people feel very upset about how it looks, which can affect self-esteem and confidence. You can choose to hide poliosis with hair dye or wear a hat, headscarf, bandana, or wig. Poliosis occurs when the affected hair follicles have very little to no melanin.

Poliosis may remain stable, but the hairs can repigment in some situations such as alopecia areata and medication-induced. Poliosis may occur because of an inherited defect in melanisation, or due to destruction of the pigment cells at the base of the hair. By Rachael Zimlich, BSN, RNZimlich is a critical care nurse who has been writing about health care and clinical developments for over 10 years. There are also many well-documented historical reports of people suddenly experiencing poliosis due to extreme psychological stress, pain, or disease. A 2013 review of many of these reports was published in the International Journal of Trichology.

All hair is naturally white, but melanin develops before birth to give hair its color. Different hair colors contain varying amounts and types of melanin. Poliosis is a rare condition that causes a white streak in the hair, affecting both adults and children. Poliosis itself is simply a harmless lack of pigment in hair follicles, which causes them to become white or gray.
Some people say that psychological trauma, physical shock, or other stressful experiences cause poliosis to occur, sometimes overnight. Guts (Berserk) develops a Mallen streak after donning the Berserker Armor, presumably due to stress. The main character Jio Fleed of the Satan 666 manga series seems to have the condition. In DC Comics one of Batman's Robins, Jason Todd, is sometimes portrayed with a white forelock. The character of Lily Munster in the American sitcom The Munsters has two prominent Mallen streaks. © Copyright 2024 Healthgrades Marketplace, LLC, Patent US Nos. 7,752,060 and 8,719,052.
If the skin is also affected, wearing sunscreen and protecting the skin with hats or long clothing is necessary. Some people may feel upset about their white hair, which can affect their self-esteem and confidence. They can use hair dye or wear a hat, bandana, headscarf, or wig. Signs of poliosis include one or more patches of white hair on hairy parts of the body. Poliosis often affects hair on the scalp, but can also affect the eyebrows, eyelashes, or other parts of the body that are covered with hair. Required poliosis is when external factors lead to the depigmentation of a patch of hair.

While poliosis poses no health risks, its visible nature can have emotional and psychological impacts. Some people with poliosis choose to leave their hair as is, but others may not feel comfortable with the visible difference. Poliosis is a permanent condition caused by a lack of melanin and melanocytes, which leads to permanent color loss. However, it is simple to make it less noticeable if a person wishes to do so. Talk to a doctor if the color loss is new or if white skin patches are spreading.
Always consult a medical provider for diagnosis and treatment. There seem to be some medical treatments that can reverse poliosis. Poliosis can, therefore, be a helpful warning sign for someone to seek treatment before an eye conditions develop. Melanoma is a skin cancer arising from the cells that provide color to the skin. In certain cases of melanoma, poliosis can be the first sign of this cancer. Management generally involves temporary solutions to cover up the white patch.
What are the clinical features of poliosis?
In some cases, vitiligo patches can become itchy, but pain or other serious complications are unusual. The word for this condition comes from the Greek word “pilios,” which means “gray.” Melanin is the substance that gives hair its color. People with poliosis have a decreased level or complete lack of melanin in the roots of affected hairs, also called hair follicles.
It occurs due to a lack of melanin (a substance that produces pigmentation in your hair, skin, and eyes) in certain hair follicles, causing the hair growing from those follicles to be white. The characteristic symptom of poliosis is a white streak or patch in the hair. It can affect patches of hair on the head, eyebrows, eyelashes, arms, surrounding skin, and scalp.
It is impossible to permanently change the shade of the hair affected by poliosis. If a person wishes to make their poliosis less obvious, the basic and economical choice is to color the hair that has been lightened by the condition.

While poliosis is not harmful, it can be a sign of various conditions that are. In the study, 42 percent of the children with vitiligo reported having at least one relative with a thyroid or autoimmune condition or both. As poliosis is known to be a side effect of at least one chronic inflammatory disorder, its appearance could serve as a warning sign for any number of related conditions. Glancing into the bathroom mirror and noticing streaks of white hair that were not there before can be a worrying experience. As with many other things in life, poliosis is less scary when it is understood.
Research published in the Journal of the American Academy of Dermatology, dating back to 1981, found that poliosis was more common in people experiencing the eye condition uveitis. For this reason, it is a good idea for someone to get an opinion from a doctor when signs of poliosis first show up. There’s one report of a laser treatment that improved poliosis and vitiligo in the eyebrow. The treatment involved 44 sessions of laser, which yielded a 75% improvement. This represents one case and requires intense treatment, though, so more research is needed. If you have any concerns with your skin or its treatment, see a dermatologist for advice.
Johnny Depp’s character has it in the movie “Sweeney Todd.” Singer Bonnie Raitt has it naturally. There are no known treatments to add color to depigmented hair permanently. Just as vitiligo can make your body attack the cells that produce melanin in your skin, it can also affect the melanin that gives your hair color. Some people with vitiligo may develop patches of white or gray hair where melanin has been lost. Poliosis—also called poliosis circumscripta—is a condition in which a patch—or patches—of white hair occur when the rest of the hair color is normal. Poliosis occurs when there isn’t enough melanin in a certain area of hair follicles, leading to a lack of pigment in the hair that grows from those follicles.
