Poliosis is a rare hair disorder that results in the loss of color in hair.
It is also called Mallen streak or white forelock.
The condition can cause a patch of white hair to form on the scalp, eyebrows, eyelashes, and other areas of the body.
But poliosis does not cause physical discomfort.
Furthermore, it said poliosis involves other health conditions.
It also has a negative effect on the self-esteem of young people, both physically and mentally.
In this blog post, I will discuss everything you need to know about poliosis.
Equally important are topics such as causes, symptoms, and treatment options, which I will discuss.
Let’s start with pigmentation of the scalp hair…
Pigmentation of hair
The human hair has a distinct feature of pigmentation.
The human hair shaft has three layers:
Firstly, the medulla is the innermost layer.
While the cells in it are not closely packed together, it creates air pockets.
The next layer, the cortex, contains melanin granules that give hair its color.
Thirdly, the outer layer or cuticle is a thin transparent scale.
In fact, it acts as a cover that protects the cortex.
What factors influence hair color?
Let’s focus on a pigment called melanin.
Human hair color affects the amount of pigment called melanin present in the cortex.
This melanin is a pigment manufactured by cells in your body-skin called melanocytes.
The type and distribution of melanocytes will determine the human hair colors.
Primary and secondary pigment cells.
Human hair follicle contains two types of melanocytes.
They are the primary pigment cells and the secondary pigment cells.
1.The primary pigment cells are at the base of the hair follicle that produces eumelanin.
Eumelanin is a black or brown pigment that gives hair its natural color.
2. The secondary pigment cells are in the upper part of the hair follicle. It is this follicle that produces pheomelanin.
Pheomelanin is a red or yellow pigment that gives hair its ginger, red, or blonde color.
Poliosis is a disorder that affects the color of hair on your scalp.
One possible cause is a lack of melanocytes, which are the cells that give hair its color.
Other causes include over-production of melanocytes, or an abnormal distribution of melanocytes.
The end result causes your hair to turn gray or give you white hair.
Finally, did you know poliosis, which comes from the Greek word “polios”?
It means gray!
Another possible reason for premature graying is the production of hydrogen peroxide.
You find this production carried out in hair follicles.
In 2009, researchers in Europe revealed hair follicles had hydrogen peroxide in it.
For this reason, this chemical build up over time can cause gray hair.
What exactly is poliosis?
As I previously explained, poliosis is a hair disease in which a pigment called melanocytes disappears in hair follicles.
This causes white patches on the scalp, brows, lashes, and other body regions.
Poliosis is a rare condition that affects both men and women of all ages.
While it is non-life threatening, poliosis can sometimes involve other health conditions.
What are the symptoms of poliosis?
The most common cause of poliosis is a genetic mutation that affects the hair follicles.
This type of underlying causes are usually congenital, meaning it is present at birth.
However, poliosis can also happen later in life.
It happens when certain medical conditions or treatments cause it.
There are several types of poliosis, each with its symptoms.
Acquired poliosis is often reversible.
Due to possible causes, including eye diseases and autoimmune disorders.
Another form of acquired poliosis is Blepharitis.
Notably, clogged oil glands that cause eyelid swelling.
Vitiligo is an autoimmune condition.
When the body’s immune cells attack and destroy melanin-producing skin cells.
Thereupon causing white patches (or “white Nevi”) to appear.
Although researchers aren’t certain what causes vitiligo, having a specific gene or family history of autoimmune condition might raise one’s risk.
Alopecia areata is another type of poliosis that causes patchy loss of hair.
It is also known as one of the causes of slow graying of hair on the scalp.
This is the sort of poliosis that plagued celebrities such as Naomi Campbell, Nicholas Cage, and Jada Williams.
Androgenetic alopecia is a type of poliosis that causes loss of hair in both men and women.
There is permanent scalp hair loss, and in some cases baldness.
As you get older
There are many other causes of poliosis, but the most common cause is ageing.
As we age, our hair follicles become less active and produce less pigment.
This is why many people develop gray hair or white hair as they get older.
Medical condition and medications
Other causes of poliosis include certain medical conditions and medications.
Such medical conditions as tuberous sclerosis, piebaldism, and Waardenburg syndrome.
And, medications like chloramphenicol and cetuximab are possible causes of poliosis.
There are also many well-documented historical reports of people experiencing poliosis.
This is due to extreme psychological stress, pain, or disease.
A 2017 review of medical literature found evidence that hair loss, including poliosis, is due to alopecia areata.
Poliosis can occur in anybody.
But it occurs more in people with certain genetic conditions.
One example of this is Waardenburg syndrome.
This is a disorder that can cause hearing loss and changes in hair color, epidermis and eyes.
People with this condition often have white forelock hair.
This is white hair that grows in a line across the forehead.
Hair color changes with age, but white hair can show up at any stage of life.
Even teenagers and people in their 20s may observe a few strands of white hair.
What diseases, if any, are due to poliosis?
While poliosis appears not harmful, it can be an early warning sign of more serious health issues.
Here are some harmful health conditions that poliosis may be the cause:
Poliosis, which is an inherited disease, can cause melanoma.
This is because people with poliosis have an increased risk of developing melanoma.
In fact, one medically reviewed study found anyone with vitiligo was six times more likely to develop melanoma.
There is also a link between poliosis and certain types of cancer, such as lymphoma.
This is because people with poliosis have a higher increased risk of developing cancers.
Poliosis can also be a symptom of autoimmune diseases. such as alopecia areata and vitiligo.
These diseases occur when the body’s immune system attacks healthy cells by mistake.
This can cause hair loss and premature white hair, as well as other symptoms.
According to the Journal of the American Academy of Dermatology, poliosis can cause certain eye issues.
Two such conditions are uveitis and glaucoma.
Uveitis is a condition that causes inflammation of the uvea, which is the middle layer of the eye.
Glaucoma is a condition that damages the optic nerve.
In fact, this nerve carries information from the eye to the brain.
While these conditions are not life-threatening, they can lead to blindness.
Especially if left untreated.
Poliosis can also be a sign of an overactive thyroid.
The thyroid is a gland in the neck that produces hormones that regulate the body’s metabolism.
An overactive thyroid can cause several symptoms, including losing your hair.
While an overactive thyroid is not life-threatening, it can be uncomfortable.
Therefore, you should seek medical help.
Diseases that cause inflammation
As you can see, there are many possible causes of poliosis.
Poliosis is a late side effect of Vogt Koyanagi Harada disease (VKH)y.
This is an inflammatory disease that attacks the nervous system, eyes, and inner ear.
The treatment for VKH disease includes steroids, but the poliosis is irreversible.
Other diseases, such as Lupus erythematosus and sarcoidosis, cause inflammation leading to poliosis.
Erythematosus causes inflammation to the body’s surfaces, including joints and organs.
At the same time, sarcoidosis causes inflammation of the lungs and lymph nodes.
While these diseases can be serious, they are treatable with medication.
When to see a doctor
It is important to consult your doctor when you notice sudden changes in your hair.
Including changes in hair color, premature gray hair, and excess hair loss.
This is especially true if you notice any other unusual symptoms.
Your doctor can tell if you have poliosis and, if so, what is causing it.
They can also provide you with treatment options to manage your symptoms.
How do you treat poliosis?
There is no cure for poliosis.
But, there are treatments that can help manage the symptoms.
Topical corticosteroids are a type of medication that you used to treat poliosis.
You apply these steroids to the affected area of your body’s skin.
They can help reduce inflammation and improve the appearance of the body’s skin.
Corticosteroid injections are another option for treating poliosis.
You inject the corticosteroid into the affected area of your skin.
They can help reduce inflammation and improve the appearance of the skin.
Light therapy uses ultraviolet light to improve the appearance of the skin.
Moreover, this is another type of therapy that treats poliosis.
It can help reduce inflammation and improve the appearance of the skin.
In some cases, surgery may be an option for treating poliosis.
Vitiligo surgery is an alternative treatment for poliosis.
This treatment, which is a surgery, can improve the appearance of the skin.
It works by transplanting pigment cells from another body surface.
Next, you cover this affected area with the pigment cells.
This type of surgery is usually only done if other treatments have not worked.
Epidermal grafting is another type of surgery used to treat poliosis.
In this treatment, the affected areas receive a grafted top layer epidermis, from another part of the body.
This can help improve the appearance of the body surface.
Skin camouflage is a type of makeup. It is used to mask the affected area of the body.
Equally important is that this type of makeup can help improve the appearance of the skin.
It is important to note that poliosis is not contagious and cannot spread from person to person.
Poliosis care and treatment
Other ways where you can manage the conditions include:
- Sunblock: This can prevent the afflicted region of skin from developing darker.
- Wear clothing : This helps prevent the affected body surface from getting darker.
- Avoiding stress: Helps prevent the condition from getting worse.
- Getting enough sleep: This can prevent the disease from worsening.
- Eating a healthy diet: It can help improve the appearance of the surface body.
- Hair dyes: This can help cover up the affected area of hair.
- Hair transplants: It will help cover up the affected area of hair.
Is there such a thing as a hair birthmark?
Yes, such a birthmark is a type of poliosis present at birth.
Hair birthmarks are not contagious and cannot spread from person to person.
However, genetics is only one factor causing this type of poliosis.
As mentioned earlier, all poliosis treatments can also help improve the appearance of the body surface for people with hair birthmarks.
What causes your eyelashes to turn white?
The natural aging process handles white eyelashes in most cases.
Although they may hint at an underlying medical issue.
Many of these issues are not serious.
However, thyroid problems and other conditions, such as hypothyroidism, need medical attention.
Let’s look at some likely reasons for causing white eyelashes.
The ageing process is the most common cause of white eyelashes.
As you age, your hair follicles produce less melanin, the pigment that gives color to your hair.
This can happen gradually or suddenly.
Certain medical conditions can lead to white eyelashes, including:
– Hypothyroidism: This occurs when the thyroid gland doesn’t produce enough of hormone thyroxine.
– Vitiligo: This is a condition that causes patches of flesh to lose their color.
– Alopecia areata: This is a condition that causes hair loss.
-Blepharitis : It is the inflammation of your eyelid caused by:
- Excess oil in your body surface
- A reaction to makeup
Eyelashes that turn white, fall out, or grow in a strange pattern are signs of blepharitis.
Lack of vitamin B12
Vitamin B12 is essential for the operation and improvement of your nervous system.
In addition, it is important for formation of red blood cells.
A lack of vitamin B12 can lead to anemia, which can cause your eyelashes to turn white.
Other possible causes of white eyelashes include:
– Trichotillomania: This is a condition that causes people to pull out their eyelashes.
– Trauma: An injury to your eye or eyelid can cause your eyelashes to fall out.
– Burns: Severe burns can damage the hair follicles and cause hair loss.
– Chemotherapy: Cancer treatment can cause your eyelashes to fall out.
If you have white eyelashes and want to know more, consult your doctor.
They can help diagnose the cause and recommend treatment options available.
In most cases, white eyelashes don’t need treatment.
If your white eyelashes are due to a medical condition, then treatment depends on the cause.
For example, if you have hypothyroidism, you’ll need to take medication to replace the missing hormone.
If you have vitiligo, you may need topical steroids.
Alternatively, immunotherapy injections to restore the color of your skin.
There’s no guaranteed way to prevent white eyelashes, but there are things you can do to reduce your risk.
For example, if you have hypothyroidism causing white eyelashes, medication can help.
Also eyelash serum or growth product to help prevent eyelash loss.
And if you’re still concerned about its appearance, try using tinted mascara or an eyelash dye.
Both work as well.
What causes white eyelashes in children?
There are many reasons why children can get white eyelashes, which are similar to adults.
Some possible causes include: thyroid disorder, vitamin B12 deficiency, poliosis, blepharitis, genetics or hormones, and vitiligo.
Likewise, alopecia areata is another possible cause of children’s white eyelashes.
Senile hair graying has interested the attention of scientists and the business world.
With intentional scientific and commercial goals.
However, there are no perfect solutions for gray hairs available on the market yet.
While many hair dyes claim to be effective and last for a certain amount of time, they often do not meet those claims.
If you have white or gray hair and it appears out of the blue, it is best to see a doctor.
While poliosis itself is not harmful, it can be a sign of a possible underlying condition.
In this article, I discussed many conditions that can trigger poliosis, causes of hair growth, and hair graying.
As well as medications and psychological stressors that can cause it.
I hope you found this information useful and informative.
