What is seborrheic dermatitis?

Seborrheic means sebaceous, and derm refers to skin. Seborrheic dermatitis is a condition in which the scalp becomes red and flaky. It can affect people of any age group. When this condition affects babies, it is called a cradle cap. It covers the scalp with greasy crust and scales. In simple words, it is a greasy kind of dandruff. Seborrheic dermatitis is not just limited to the scalp. It can affect various parts of the body, especially those that are excessively oily, like the face, chest, abdomen, and folds of the skin.

What are the possible triggers of seborrheic dermatitis?

The causes of seborrheic dermatitis are not known or understood, but some things can trigger it and make this condition worse. Those possible triggers are health issues, depression, weather, hormonal changes, and oily skin.

Health issues: Some medical issues like Parkinson's disease, a compromised immune system, HIV Aids, heart disease, cancers, and certain medications increase the chance of getting seborrheic dermatitis.

Depression: People with depression and high stress levels have a higher chance of suffering from this skin and scalp condition. So, if your mental health has been low lately and you are under stress or going through PTSD, you are at a higher risk of getting seborrheic dermatitis.

Weather: It has been observed that the cold and dry weather triggers this condition or aggravates it. Summertime usually keeps it under control because the heat can kill a certain type of yeast that lives on the skin and causes this condition.

Hormonal changes: Another factor that increases the risk of this condition is hormonal changes in the body. There is not much research on exactly how it triggers seborrheic dermatitis, but it certainly is a major risk factor.

Alcohol: Over-consumption of alcohol can trigger this condition as well. Skincare products containing alcohol can also be a problem for people who tend to get this condition.

Oily skin: This condition occurs on parts of the body that are excessively oily, and hence oily skin is a major trigger for seborrheic dermatitis.

What are the symptoms of seborrheic dermatitis, and when to see a doctor?

If you notice white or yellowish crust on your scalp and skin, which is also oily, you probably have seborrheic dermatitis. You will also notice redness on the affected area and experience itchiness. Another major characteristic of this condition is excessive and stubborn dandruff. However, seborrheic dermatitis can be confused with other skin conditions like rash, allergy, eczema, psoriasis, and rosacea because they have some similarities in them. A biopsy can confirm whether you have seborrheic dermatitis or not. Babies usually heal by themselves as they grow a little, even though this condition can hit them back later in life. However, adults suffering from mild or severe symptoms of seborrheic dermatitis should see a doctor, especially if it starts affecting their everyday life and home remedies fail to help them.

How to deal with seborrheic dermatitis?

Seborrheic dermatitis can be treated with some tips, techniques, lifestyle changes, and better skincare habits.
