Seborrheic dermatitis is a skin condition that affects millions of people worldwide. And for sufferers, knowing what causes seborrheic dermatitis flare-ups and how to avoid them, is very important information.
What is seborrheic dermatitis?
Seborrheic dermatitis is a type of eczema that affects the areas of the body where there are a lot of sebaceous glands. The areas usually affected include the sides of the nose, inside of the ears, scalp, eyebrows, and behind the ears. In some cases, the armpits, groin, and chest can also be affected.
Possible Causes
Malassezia
Doctors don’t know the exact cause of seborrheic dermatitis. Doctors believe that it’s caused by an overgrowth of malassezia, which is a type of fungus that lives on the skin. This overgrowth then triggers a response in the body, and causes the symptoms.
Oily Skin
Another possible cause of seborrheic dermatitis is having oily skin. This is because malassezia thrives on oily skin, which can cause the fungi to grow out of control.
‘Cradle Cap’ in Infants
Seborrheic dermatitis can affect both infants and adults. In infants, it’s known as cradle cap, and it causes rashes on an infant’s scalp, neck, chest, and arms.
In adults, it usually affects the scalp and parts of the head. A person can have seborrheic dermatitis, yet only experience the mild effects. However, certain things can also trigger flare-ups and make it worse.
It is important to note that having poor hygiene does not cause seborrheic dermatitis, nor is it a contagious condition.
What causes seborrheic dermatitis flare-ups?
Seborrheic dermatitis flare-ups not only cause discomfort, but also embarrassment. This is especially true for people who are adversely affected whenever they experience flare-ups.
This is why it’s important for people to be aware of what causes seborrheic dermatitis flare-ups so that they can take steps to avoid it.
Here are some of the triggers:
- Having oily skin
- Being under a lot of stress
- Lack of sleep
- Sudden hormonal changes
- Being in cold, dry weather
- A family history of seborrheic dermatitis or psoriasis
- Conditions such as Parkinson’s disease or depression
- Certain types of medication
- Having a weakened immune system
If you have seborrheic dermatitis, it would be a good idea to know what triggers your condition. This can help you manage it better, so that you can take precautionary measures in order to avoid having flare-ups.
Symptoms
The symptoms of seborrheic dermatitis can vary from person to person. Some people can experience only mild symptoms, while others experience more severe symptoms that can cause embarrassment, and even anxiety.
In infants, the symptoms of seborrheic dermatitis usually appear as flaky, greasy patches on the scalp known as cradle cap. It’s also possible for infants with seborrheic dermatitis to have rashes that spread from their scalp to their neck, chest, torso, as well as the arms, and the groin area.
