Seborrheic Dermatitis is usually a scalp and skin problem that leads to redness, scaly patches of the skin and dandruff. It is a chronic form of eczema and occurs in those parts of your body where there are a number of sebaceous glands including the scalp, nose, face, and upper back. The effects are more severe in cold and dry climates and during periods of extreme stress; this could also trigger off extreme cases of telogen effluvium. It is more common among infants and adults between 30-60 years of age. With infants, it usually develops within the first few months and then disappears over a few weeks or months. In adults, however, it could clear and reappear as part of a process that could go on for years. 

Seborrheic dermatitis is highly unpredictable. It could last for the entire duration of your life with sporadic outbursts that could continue to bother you from time to time. At the same time, you might have to go through those phases where you might be perfectly normal and not display any symptoms of the disease at all. On the other hand, there will be those times when you might have flare-ups and the discomfort and pain become unbearable.  When it comes to seborrheic dermatitis vs dandruff while dandruff is restricted to the scalp while seborrheic dermatitis could affect other body parts as well.

The solution is to build a health regime that allows you to minimize the problems to help you lead as normal a life as possible. You will be able to identify the triggers and take steps in advance to help deal with your condition. The crucial objective is to ensure that the condition does not aggravate and lead to any serious medical complications. 

What Causes Seborrheic Dermatitis? 

Seborrheic Dermatitis occurs as a result of an inflammatory reaction to an abnormal increase in yeast Malassezia, which proliferates rapidly on the surface of the skin. This increase in the production of Malassezia creates an immune reaction in the body. The yeast survives on lipids (fats/oils) and increases expeditiously if a good quantity of fatty acids is present in and around it. It could also flourish as a result of an excessive amount of scalp oil which might force the skin to turn red and greasy. 

Hormonal changes that take place in the body of the mother during pregnancy might also lead to this condition. The changing hormonal levels may lead to increased secretion from the oil glands and lead to an itchy scalp. 

Certain medical conditions like acne, Parkinson’s disease, alcoholism, epilepsy, alcoholism, HIV or recovery from a stroke may also trigger seborrheic dermatitis. The following could also cause seborrheic dermatitis:

  • Hormonal changes
  • Stress
  • Soaps, Harsh hair products, shampoos, dyes
  • Medications such as interferon, lithium, and psoralen.

Who Is At A Risk Of Seborrheic Dermatitis? 

If you have a weak immune system, you could be susceptible to seborrheic dermatitis. People who suffer from oily skin problems are the most likely to have seborrheic dermatitis. This gives rise to the theory that the condition could be connected with sex hormones like androgens. There is a possibility that individuals suffering from neurological disorders and psychiatric issues could develop a seborrheic dermatitis scalp sometime in the future. The likelihood increases manifold if somebody closely related to the family has it. Apart from this, the list of possibilities also includes certain high-risk individuals including the following:

  • Obese people 
  • Persons suffering from weakness & fatigue
  • People with skin issues or those suffering from scalp psoriasis or acne
  • Those suffering from stress
  • Individuals under medication with specific drugs like lithium
  • People treating their hair with harsh using chemical products 
  • Persons with serious medical conditions like Parkinson’s disease, HIV and AIDS.

Genetics is one of the main reasons for seborrheic dermatitis. Hormonal changes or yeast overgrowth could also lead to such issues. 

Ways To Diagnose Seborrheic Dermatitis 

We need to separate the symptoms that are typical of seborrheic dermatitis from other similar issues such as scalp psoriasis. There is a simple way of diagnosing it as there is a typical way in which the lesions are scattered over the scalp; they also develop in a specific manner. They are normally spread out in those areas where more oil-producing glands are present. These include the scalp, ears, upper chest, eyebrows, back, and genitals. 

In rare cases, biopsies might be required and a portion of the skin is extracted for further analysis. This is done to eliminate the possibility of infections that display similar symptoms like fungal infections among other things. You might also have to go for a blood test if the expert suspects that there is a possibility of it being triggered by some underlying health condition. 

While psoriasis is very similar to seborrheic dermatitis there are some marked differences. Seborrheic dermatitis appears as yellowish-white lesions that are greasy and can be removed easily. Psoriasis on the other hand is silvery-white and tends to bleed when they are scratched. However, there might be those rare situations when the individual suffers from more than 1 condition at any point in time. One such example is sebopsoriasis, a condition where psoriasis and seborrheic dermatitis overlap. Let’s take a look at the symptoms of seborrheic dermatitis:

  • Itchy white flakes are seen on your scalp. The flakes drop down from your hair to your neck and shoulders. 
  • Infants tend to develop crusty skin on their scalps. Though they do not normally itch, scratching can escalate into bleeding and mild infections. 
  • Scaly redness can be seen near the eyelids.
  • Pinkish scales appear on both sides of the face.
  • Flaky ring-like patches might be seen on the scalp or chest. 
  • Swelling and inflammation of hair follicles on cheeks and upper half of trunk.
  • One might experience redness and mild swellings in the folds of the genitals, breast, and armpits.

Medical Treatments For Seborrheic Dermatitis
