Seborrheic Dermatitis – An Extensive Guide to Causes, Symptoms, and Treatment Methods

Skin conditions can appear from birth, with dermatitis being one of the most well-known. A type of dermatitis is seborrheic dermatitis, which is frequently encountered globally. One of the reasons for the increase in cases is environmental pollution, but it’s not the only one.

What is seborrheic dermatitis and what are its characteristics? It is a chronic form of eczema that, in the first phase, can resemble other skin conditions. This makes its diagnosis a bit more difficult, but not impossible. However, modern medicine has made advancements regarding it, and it can now be controlled.

In the following article, we will present useful information about seborrheic dermatitis, who can be affected by it, and how it is treated.

Seborrheic Dermatitis – Important Aspects of This Condition

Seborrheic dermatitis is a chronic inflammation of the skin, characterized by white, oily, or dry scales or flakes. Because it can be caused by certain bacteria, we might think this condition is contagious. Therefore, it’s good to know from the outset that seborrheic dermatitis is not contagious. Another important aspect is that this type of skin disorder is still being researched to determine its causes.

Very often, seborrheic dermatitis is confused with other dermatoses such as psoriasis or pityriasis. Therefore, it is recommended to see a doctor for diagnosis. As it can occur in both children and adults, we must also be aware of the risk factors associated with seborrheic dermatitis.

Seborrheic Dermatitis and Its Main Risk Factors

Seborrheic dermatitis is a disease that can appear due to various causes. It can also be aggravated by certain factors, including:

• A weakened immune system;
• Various skin conditions, such as acne and rosacea;
• Certain medications for various illnesses;
• Neurological conditions, such as Parkinson’s or Huntington’s disease;
• Depression and stress;
• The recovery period after other medical conditions;
• Exposure to very high or very low temperatures.

All these risk factors add to the causes that lead to the formation of seborrheic dermatitis. Although these can be multiple, not all are known. From the research conducted so far, there are, however, some quite important ones.

Seborrheic Dermatitis and Its Causes

There are several causes that underlie the appearance of seborrheic dermatitis. Besides aggravating factors, it can also be caused by:

• The Malassezia fungus, which is present on everyone’s skin but multiplies only in certain individuals;
• High levels of androgen hormones;
• Excessive sebum production by the sebaceous glands;
• Certain inflammatory reactions;
• Genetic factors;
• The use of skincare products with high irritating potential.

Due to some of the factors mentioned above, such as the Malassezia fungus, the question has arisen whether seborrheic dermatitis is contagious. Given that this fungus exists in everyone, the answer is no, it is not transmitted. Also, in adults, stress can be one of the most common causes of this type of dermatosis.

To prevent the onset of seborrheic dermatitis or to keep its symptoms under control, many people turn to natural remedies. Natural treatments, such as tea tree oil or aloe vera, can help alleviate the symptoms of seborrheic dermatitis.

Aloe vera is an important source of antioxidants, contributing to maintaining healthy skin. A product based on this miracle plant is Aloe Vera Gel, which acts both externally and internally. It has beneficial effects on the immune and nervous systems, especially since seborrheic dermatitis in adults can manifest during stressful periods.

With over 200 vitamins, minerals, and antioxidants, aloe vera has numerous health benefits. To enjoy all of them, you only need to consume 100 ml every day. Discover its unique properties too by choosing a natural and ecological gel!

How Does Seborrheic Dermatitis Manifest on the Scalp, Face, or Other Body Parts?

Often, seborrheic dermatitis resembles other skin diseases, including psoriasis and acne. From this perspective, we must know that they can be two of its causes. Therefore, these skin conditions have very similar manifestations.

The symptoms of seborrheic dermatitis depend heavily on where it appears. Among the signs we should not ignore are:

• scales, flakes, or dandruff on the scalp, eyebrows, and chin;
• white or yellowish crusts on the scalp, face, sides of the nose, eyebrows, ears, eyelids, elbows, and chest;
• redness and itching or pruritus of the skin.

Complications of Seborrheic Dermatitis

Seborrheic dermatitis can worsen under certain circumstances, especially during stressful periods, with complications including:

• changes in skin appearance, it may become thinner;
• alopecia or hair loss in areas affected by itching;
• the possibility of fungal infections around predisposed areas;
• the possibility of bacterial infections.

These do not all have to appear at the same time. Moreover, they can manifest differently in adults and children, even in infants. Even in the case of fungal or bacterial infections, seborrheic dermatitis is not transmitted.

What Does Seborrheic Dermatitis Look Like on Different Parts of the Body?

Many people wonder on which parts of the body seborrheic dermatitis appears. Judging by the multitude of images and photos online, it often manifests on the scalp, face, and hands. Since it can resemble other skin conditions, such as acne or psoriasis, it is recommended to see a doctor for a clear diagnosis.

Seborrheic Dermatitis on the Scalp

Frequently, seborrheic dermatitis can appear on the scalp. In this situation, we can expect symptoms such as the appearance of flakes, itching, redness, dryness, and inflammation. In more severe cases, it is also accompanied by dandruff.

Because it can be confused with dandruff, we need to know how to differentiate between the two skin conditions. In seborrheic dermatitis, dandruff episodes will often be accompanied by itching and redness of the affected area. It can also be accompanied by alopecia or hair loss due to excessive scratching.

Seborrheic Dermatitis on the Face

Besides the scalp, it can also affect the face. Predisposed areas include:

• the hairline on the forehead;
• the area around the eyebrows;
• the free edge of the eyelids, where seborrheic blepharitis occurs;
• the nasolabial folds;
• the chin.

Seborrheic dermatitis can also appear on the face, on both cheeks, and behind the ears.

Seborrheic Dermatitis on the Body

On the body, seborrheic dermatitis can predominate on the chest. It can also manifest as red, flaky patches in the armpits and groin folds. However, in these areas, it can often go unnoticed. In most cases, adults are affected by this dermatosis on the chest.

Seborrheic Dermatitis on the Extremities

Of all the parts of the body, hands are often predisposed to pathogens. Therefore, seborrheic dermatitis can also settle on the extremities, even the feet. However, in this case, it often needs to be investigated to rule out atopic dermatitis or contact dermatitis.

In addition to these manifestations, we must also consider the people it can affect. Seborrheic dermatitis can occur in both children and adults. In both cases, there are similar and different symptoms for each affected category.

Seborrheic Dermatitis and Who It Affects

Seborrheic dermatitis seems to affect adult males more. This is because their sebaceous glands are more active. However, women can also suffer from this type of dermatosis, especially those whose androgen hormones are more active. This is why the disease is associated with inflammatory seborrhea flare-ups.

Children can also suffer from seborrheic dermatitis, especially infants. In the latter, it can appear from the first months of life in the form of crusts on the scalp.

Seborrheic Dermatitis in Infants

Seborrheic dermatitis in infants can appear in the first months of life and is also called infantile seborrheic dermatitis. Popularly, it is known as cradle cap and mainly manifests on the head, in the scalp area. However, it can also be present on the forehead, at the nape of the neck, or on the anterior fontanelle. Furthermore, seborrheic dermatitis can also settle on the face, in the cheek area. On the body, it can appear in the large folds, such as the axillary regions and behind the knees.

If we look at photos and images of seborrheic dermatitis in newborns and infants, we realize that it can resemble an irritation followed by crust formation. The good news is that, although it progresses slowly, in many cases, it resolves on its own in about two months. However, during its manifestation, complications such as Leiner-Moussous desquamative erythroderma can occur.

Seborrheic Dermatitis in Children and Adults

In children and adults, seborrheic dermatitis manifests as patches covered with thinner or thicker white-yellowish scales. Most often, they appear in areas adjacent to the sebaceous glands, such as:

• in the head region, where seborrheic dermatitis can resemble psoriasis or dandruff;
• on the face, around the eyebrows, between them, around the eyes and in the nasolabial folds, as well as on the chin;
• on the chest;
• on the extremities, especially the hands.

If on the head seborrheic dermatitis resembles psoriasis, on the face, it can be confused with acne. The recommended course of action is to consult a doctor for diagnosis. The dermatologist can recommend topical products, in the form of creams and ointments, as well as a diet that helps with seborrheic dermatitis.

Vitamins for Seborrheic Dermatitis and Other Natural Remedies

Seborrheic dermatitis is recurrent. It can appear and disappear, with periods of worsening. These are associated with cold or very hot weather. Therefore, it is necessary to see a dermatologist for diagnosis. They will be able to tell if it’s dermatitis or other conditions such as psoriasis, pityriasis, acne, or rosacea. Remedies often consist of topical products, but certain natural treatments can also help us keep it under control.

Medical Recommendations for Seborrheic Dermatitis

Initially, the doctor may recommend shampoos, creams, and ointments that should be applied topically. These are often based on corticosteroids such as hydrocortisone, clobetasol, and desonide. The recommendation is not to use them long-term. Instead, they can be used alternately with antifungal or antimycotic products.

Natural Treatment for Seborrheic Dermatitis

Natural remedies for seborrheic dermatitis can include taking certain vitamins and a well-controlled diet. Whether we opt for natural juices or capsules, we have several easily administrable options.

Forbidden and Allowed Foods in Seborrheic Dermatitis

Among the forbidden foods in this condition are those rich in sugar, carbohydrates, and saturated fats. These are most often found in processed products, such as processed meats and snacks. Alcohol and caffeine can also worsen the signs of this condition.

On the list of allowed foods in seborrheic dermatitis, we can include:

• vegetables, such as spinach, avocado, broccoli, tomatoes, and carrots;
• fruits, such as strawberries, apples, oranges, and sea buckthorn;
• fish.

These are packed with vitamins and antioxidants that help keep seborrheic dermatitis under control.

Among the beneficial vitamins and minerals for this condition are:

• vitamins A, C, and E, which are powerful antioxidants and whose effects are to protect the skin and reduce inflammation;
• carotenoids, which fight free radicals and help reduce skin inflammation;
• flavonoids, which protect the skin against oxidative stress;
• Omega 3, which helps maintain skin health.

How to get rid of seborrheic dermatitis? It can be recurrent, appearing and disappearing at various intervals. Following a diagnosis by a dermatologist, topical products based on corticosteroids can be applied. A balanced diet, excluding foods that cause skin inflammation, can also help. Equally useful is the consumption of fruits and vegetables rich in vitamins A, C, E, and antioxidants.

In conclusion, seborrheic dermatitis is a chronic skin condition that affects adults, newborns, and children. It can be triggered by a genetic predisposition or by external factors, such as infection with various pathogens. Its main symptoms are the appearance of white-yellowish crusts on the head, at the scalp level, accompanied by redness and itching.
