Seborrheic Dermatitis
Key Takeaways
Seborrheic dermatitis is a common chronic inflammatory skin condition that causes flaking, scaling, and irritation in oil-rich areas such as the scalp, eyebrows, sides of the nose, ears, and chest.
It is the medical term for dandruff when it affects the scalp and “cradle cap” when it affects infants.
In skin of color, seborrheic dermatitis may not look bright red. It may show up as lighter patches, mild scaling, or a petal-shaped rash along the hairline and face.
For many people with deeper skin tones, the most frustrating part is what remains after the flare improves—especially light spots or uneven skin tone.
Medicated antifungal shampoos and creams are the foundation of treatment, but the best regimen often depends on where the rash is located and, for scalp disease, how often you wash your hair.
If over-the-counter dandruff treatments are not working, or if you are developing pigment changes on the face or scalp, it is worth seeing a dermatologist.
What is Seborrheic Dermatitis?
Seborrheic dermatitis is a chronic inflammatory skin condition that causes flaking, scaling, and irritation in areas of the body where oil glands are most active. Common locations include the:
scalp
eyebrows
sides of the nose
beard area
ears and behind the ears
chest
sometimes skin folds
When seborrheic dermatitis affects the scalp, many people simply call it dandruff. In babies, it is often called cradle cap.
Seborrheic dermatitis is not contagious, and it is not caused by poor hygiene. It tends to come and go over time, which means people often notice periods when it improves and then flares again.
For some people, it is mostly a scalp issue. For others, it also affects the face, ears, chest, or body folds. In skin of color, the appearance can be different enough that the condition is sometimes missed, confused with another rash, or mistaken for “just dry skin.”

A few things worth knowing
Seborrheic dermatitis affects both children and adults, but the age pattern is different. It is common in infants as cradle cap, and then becomes more common again after puberty and intoadulthood.It tends to be more common in men and may be more common or more severe in people with Parkinson’s disease, HIV, or other conditions that affect the immune system.In Black patients and other patients with deeper skin tones, it is one of the more common reasons for a dermatology visit.
Stress, illness, weather changes, and harsh hair or skin products can make flares worse.What Does Seborrheic Dermatitis Look Like?
Seborrheic dermatitis can look a little different depending on where it appears, how inflamed it is, and the person’s skin tone.
Common symptoms
People with seborrheic dermatitis may notice:
flaking or dandruff
itching
greasy or yellowish scale
mild redness or irritation
dry or scaly patches around the eyebrows, nose, ears, or beard
lighter or darker marks after the rash improves
What it may look like on the scalp
Scalp seborrheic dermatitis often causes:
loose white or yellow flakes
itching
greasy scale
irritation around the hairline or behind the ears
patches of thicker scale in more severe cases
In some people, it is mild and looks like simple dandruff. In others, it can extend beyond the scalp onto the forehead, ears, or neck.
What it may look like on the face
Facial seborrheic dermatitis often shows up in areas where oil glands are active, such as:
the eyebrows
the glabella (the area between the eyebrows)
the sides of the nose
the beard area
the ears or behind the ears
It may appear as:
flaky patches
irritation with mild scale
greasy scaling
lighter or darker patches with fine flaking
What it may look like on the body
Some people also develop seborrheic dermatitis on the:
chest
upper back
underarms
groin or skin folds
Body involvement can look like scaly patches or plaques in these oil-rich areas.
Understanding Seborrheic Dermatitis
Seborrheic dermatitis is not caused by being “dirty,” and it is not simply dry skin. It happens because of a combination of skin oil, yeast on the skin, inflammation, and individual susceptibility.
The role of Malassezia yeast
A naturally occurring yeast called Malassezia lives on the skin of many healthy people. In seborrheic dermatitis, the skin seems to react more strongly to this yeast and to the oils on the skin surface.
That reaction can trigger inflammation, which then leads to:
flaking
itching
irritation
redness or discoloration
greasy scale
Oil-rich areas are more vulnerable
Seborrheic dermatitis tends to occur where sebaceous glands (oil glands) are more active. That is why it favors the scalp, face, ears, and chest rather than the hands or lower legs.
Who is more likely to get it?
Seborrheic dermatitis can happen to anyone, but it may be more common or more severe in people who have:
naturally oilier skin
a family tendency toward seborrheic dermatitis
neurologic conditions such as Parkinson’s disease
immune system suppression, including HIV
stress or recent illness
cold or dry weather exposure
This does not mean everyone with dandruff or seborrheic dermatitis has an underlying illness. Most people do not. It simply means there are somite groups where the condition is more common or more severe.

Why seborrheic dermatitis can look different in skin of color
Seborrheic dermatitis affects people of all skin tones, but the way it looks, the way it lingers, and the way it interacts with haircare practices can be very different in deeper skin tones.
On lighter skin, seborrheic dermatitis is often described as red, flaky, and greasy.
On deeper skin tones, that classic redness may be subtle or hard to see. Instead, patients may notice:
lighter patches with mild scale
gray or ashy flaking
a petal-shaped rash along the hairline
persistent pigment changes after the rash improves
For many patients with skin of color, the condition is not just about dandruff. It is also about how visible the rash is, whether it is mistaken for another condition, and whether the skin color returns to normal after treatment.
Light spots may be more noticeable than redness
One of the most important skin-of-color differences is that seborrheic dermatitis may present with post-inflammatory hypopigmentation, meaning lighter patches left behind after inflammation.
These light spots may show up around the:
eyebrows
forehead
sides of the nose
hairline
scalp margins
In some cases, the light spots are more distressing than the flaking itself because they can last weeks to months after the active inflammation improves.
Petaloid seborrhea
A pattern called petaloid seborrhea is more commonly described in people with darker skin. This refers to well-defined petal-shaped or arc-shaped scaly plaques along the hairline or face.
This pattern can be mistaken for other conditions, including:
psoriasis
lupus
fungal infections
other inflammatory facial rashes
That is one reason facial or hairline seborrheic dermatitis in skin of color sometimes deserves a closer look rather than an automatic assumption that it is “just dandruff.”
Hair type matters for scalp treatment
This is one of the most important practical points.
Many dandruff shampoos are designed around the idea of frequent washing, but many people with tightly coiled, kinky, or textured hair do not wash their hair daily or even several times a week. That does not mean they are doing anything wrong—it simply means standard treatment instructions may not fit their haircare routine.
Some medicated shampoos can also be very drying and may increase:
scalp dryness
hair breakage
irritation
difficulty maintaining the hairstyle
So when treating scalp seborrheic dermatitis in skin of color, it is important to think not only about the medication itself, but also about:
how often the person washes their hair
whether the product is drying
whether a leave-in or oil-based option makes more sense
whether the treatment is realistic for their hairstyle and haircare routine
Why Seborrheic Dermatitis Matters
Seborrheic dermatitis is often minimized because it is common and usually not dangerous. But that does not mean it is trivial.
It can be uncomfortable and frustrating
Even “mild” seborrheic dermatitis can cause:
constant flaking
itching
irritation around the scalp or face
embarrassment from visible scale on clothing or in the eyebrows
frustration with recurring flares
It can affect confidence
When seborrheic dermatitis involves the face, eyebrows, beard area, or scalp, it can become very visible. For some people, the biggest burden is not the physical discomfort—it is the social and emotional impact.
This is especially true when the rash causes:
visible light patches
flaking around the nose or eyebrows
buildup on the scalp
chronic recurrence despite trying over-the-counter products
Pigment changes can outlast the flare
In skin of color, the rash may improve before the skin color does. That means the inflammation can be under better control, but the lighter or darker marks may still be there.
That lag can make people feel like treatment “isn’t working,” even when the inflammation is improving.
Treatment Options
Seborrheic dermatitis is treatable, but it usually needs management rather than a one-time cure. The goal is to calm the yeast-driven inflammation, reduce scale, and prevent flares.
The best treatment depends on:
where the rash is located (scalp vs. face vs. body)
how severe it is
how often it flares
your skin tone and risk of pigment changes
your hair texture and wash routine if the scalp is involved
Scalp treatment
For scalp seborrheic dermatitis, medicated antifungal shampoos are usually the starting point.
Common over-the-counter options include shampoos containing:
ketoconazole 1%
selenium sulfide
zinc pyrithione
These products work best when they are applied to the scalp and left on for several minutes before rinsing.
Important note for textured or tightly coiled hair
If you do not wash your hair frequently, or if medicated shampoos are very drying, treatment may need to be adjusted. Some strategies include:
applying the shampoo to the scalp only, rather than the entire hair shaft
following with a moisturizing conditioner
using treatment less often but more intentionally
discussing oil-based or leave-in options with a dermatologist when appropriate
In more inflamed scalp disease, a dermatologist may add:
a topical steroid solution, oil, or foam
a prescription-strength antifungal shampoo
another anti-inflammatory scalp treatment
Face and body treatment
For seborrheic dermatitis on the face or body, topical antifungal creams are often first-line. These may
include:
ketoconazole
miconazole
ciclopirox
If the area is very inflamed or itchy, a short course of a low-potency topical steroid may be used to calm things down quickly.
However, on the face—especially in skin of color—many dermatologists try to limit repeated steroid use when possible because steroids can sometimes contribute to skin thinning or pigment change.
That is why steroid-sparing medications such as tacrolimus or pimecrolimus are often very helpful for recurrent facial seborrheic dermatitis.
Newer prescription options
Some patients with persistent seborrheic dermatitis may be candidates for newer prescription treatments, including roflumilast foam (Zoryve), a nonsteroidal medication approved for seborrheic dermatitis in appropriate patients.
These options can be especially helpful when:
the condition is recurring often
the face is involved
the patient wants to minimize steroid exposure
standard over-the-counter treatments are not enough
Build a Routine
If the scalp is the main issue
A simple routine might look like this:
On wash day
Apply a medicated dandruff shampoo to the scalp
Leave it on for about 5 minutes
Rinse thoroughly
Follow with a moisturizing conditioner if needed for dryness
Between washes
Avoid harsh scratching or aggressive scraping of scale
Use scalp oils carefully if they are part of your routine, but remember that heavy buildup can sometimes make the scalp harder to treat
If your dermatologist recommends a scalp oil, steroid oil, or leave-in medication, use it as directed
If the face is the main issue
A simple routine may include:
Morning
Gentle cleanser
Prescription or over-the-counter antifungal cream if recommended
Moisturizer
Sunscreen if the area is exposed
Evening
Gentle cleanser
Antifungal cream or other prescribed treatment
Moisturizer
Common Mistakes That Can Make Seborrheic Dermatitis Worse
1. Treating the flakes but ignoring the inflammation
If the skin is itchy, irritated, or spreading beyond simple dandruff, you may need more than a basic shampoo.
2. Using harsh scrubs or scraping the scalp aggressively
Trying to “scrub off” all the scale can worsen irritation and make the skin barrier more inflamed.
3. Assuming every light patch is vitiligo
In skin of color, seborrheic dermatitis can leave lighter patches with scale—especially around the eyebrows,
nose, and hairline. Not every light patch is vitiligo.
4. Using steroid creams on the face for too long without guidance
Steroids can be helpful short-term, but repeated unsupervised use on the face is not ideal.
5. Using a dandruff shampoo that does not fit your hair routine
A product is not helpful if it is so drying that you cannot realistically use it.
When to See a Dermatologist
It is worth seeing a dermatologist if:
over-the-counter dandruff shampoos are not controlling symptoms after several weeks of consistent use
the rash is spreading beyond the scalp to the face, ears, chest, or folds
you are developing light spots, dark spots, or persistent uneven skin tone
the itching, burning, or irritation is becoming hard to manage
you are noticing hair thinning or hair loss
you have thick scale or plaques that are difficult to remove
you are not sure whether the rash is seborrheic dermatitis, psoriasis, eczema, lupus, or another condition
the condition is affecting your confidence, daily routine, or mental health
For people with skin of color, early treatment can be especially helpful because it may reduce the risk of long-lasting pigment changes and help tailor treatment to your hair and skin needs.
FAQ
-
Dandruff is the mild scalp form of seborrheic dermatitis. Seborrheic dermatitis is the broader condition and can also affect the face, ears, chest, and body folds.
-
No. It is not caused by being unclean. It is related to inflammation, skin oil, and the skin’s reaction to yeast on the skin.
-
Yes. In skin of color, seborrheic dermatitis may leave lighter patches after inflammation, especially around the face or hairline.
-
Some medicated shampoos are drying, especially for people with textured, tightly coiled, or chemically treated hair. That does not mean the treatment is wrong—it may just need to be adjusted to your hair type and wash routine.
-
It can sometimes be associated with temporary shedding if the scalp is very inflamed, but it is not usually a primary scarring hair loss condition. If you are noticing significant thinning, patchy hair loss, or scalp pain, you should get evaluated.
-
It often comes and goes over time. Many people can control it very well, but it is usually managed rather than permanently cured.
