We’re breaking down everything you need to know about seborrheic dermatitis, from what it is and its symptoms to shutting down a few common myths, and of course, how to know if you actually have it. Let’s get into it.
What Are The Signs?
You may be experiencing seborrheic dermatitis if your skin, eyebrows, scalp, or facial hair has dandruff, irritable skin patches, or flakes, according to the Mayo Clinic. More specifically, and on the verge of TMI, oily skin with flat white or yellow scales may also be a sign.
When it comes to rashes, it’s likely they’ll show up in a ring-like form (which is called petaloid seborrheic dermatitis). For the melanated folks, rashes may appear darker or lighter (per the National Eczema Association, people of color may get a more intense flare-up with lesions on the hairline and discoloration), while those with fair skin may experience red rash areas.
Where Is It?
While seborrheic dermatitis can occur on various body parts, it’s frequently seen on the scalp, according to the NEA. The Mayo Clinic notes that the condition also pops up on oily facial and body areas like the edges of one’s nose, eyelids, and eyebrows, as well as the chest and ears. Skin can appear inflamed with rashes and patches, and the scalp will typically battle with relentless dandruff.
Seborrheic dermatitis can be super irritating and frustrating, but fortunately, if you’ve been diagnosed, it doesn’t lead to permanent hair loss, and it isn’t contagious, The Mayo Clinic states. In fact, with doctor-prescribed treatment or products like special shampoo, it could disappear or at least reduce flare-ups.
What Triggers It?
It’s difficult to pinpoint what specifically causes the condition. The Mayo Clinic points out that it could arise thanks to too much oil in the skin or the presence of Malassezia, a type of fungi. Commonly, things like fatigue, weather changes, and stress also play a role. More serious conditions that can trigger it range from Parkinson’s and depression to HIV, as well as the aftermath of life-altering events like a heart attack.
Bronchitis, strep throat, the flu, tonsillitis, and ear and respiratory infections are also known to cause flare-ups, along with skin issues like bruises, sunburns, scratches, and bites, per the Cleveland Clinic.
Interestingly enough, the NIH notes that seasons changing has a role too. Seborrheic dermatitis can disappear in the summer months, and then make a comeback like it never left in the winter.
Who Does It Affect?
Unlike many other things we go through as women, seborrheic dermatitis is actually more common for men, according to the NIH. It often appears for the first time in the young adult years or for those who are older than 50.
What About Psoriasis Though?
Seborrheic dermatitis is often compared to psoriasis, and for good reason. They both impact the skin, especially the scalp area. They can both also leave scaly patches on the skin, flakes on your hair, and cause itching. However, they’re not identical. Healthline notes that areas of seborrheic dermatitis flareups are typically easier to remove compared to psoriasis. Psoriasis also tends to be sorer and more tender, while seborrheic dermatitis can itch or create a burning sensation.
Let’s Clear The Air
There are a few rumors about the power of seborrheic dermatitis and what it can cause. So let’s break down the truth for a second. According to the NEA, this condition is not cancerous, nor does it indicate or increase a higher risk for cancer in the future.
Just a reminder, it doesn’t cause hair loss, nor is hair loss a symptom. If you are experiencing concerning hair loss, it is likely a sign of something else.
How Can You Treat It?
Seborrheic dermatitis can be treated pretty easily (praises be). Certain medicines like shampoos with tar, anti-inflammatory creams that include steroids, creams and shampoos with antifungal agents, or creams that feature salicylic acid, can be applied to the inflamed area to help resolve the problematic area, according to the NIH.
Just a note though: As tempting as it is to cover up scaly patches with heavy foundation or concealer, experts with the NIH actually advise against it as it can clog your pores. However, a light foundation can be used occasionally, along with skin care products that aren’t too oily to help temporarily conceal it.
A unique type of sunscreen also isn’t needed. You can use what you typically would before stepping out into the sun. And your skin soaking in a few extra rays could actually help your skin.
Should You Self-Diagnose?
As tempting as it is to make an appointment with Dr. Google, The Mayo Clinic advises you to call your actual physician if the condition interrupts your sleep, makes you lose focus throughout the day, contributes to anxiety, or simply doesn’t go away with at-home remedies. Simply put, it’s always best to check with your doctor to ensure you’re actually experiencing seborrheic dermatitis and get the treatment you need to help monitor or prevent it.
