Seborrheic Dermatitis: Symptoms and when to seek prompt medical evaluation
Seborrheic dermatitis is a type of dermatitis characterized by white or yellow, greasy, adherent scalesscales and dandruff in areas with high sebum production, such as the scalp, hairline, eyebrows, eyelids, creases around the nose, around the ears, and the chest. The skin may appear red, pink, purple, or lighter than the surrounding area, and may feel itchy, stinging, or irritated. It varies from mild forms presenting only as scalp dandruff to patterns that spread like plaques across various parts of the face and body, often cycling between improvement and worsening. If you experience oozing, pus, thick crusts, severe pain, redness, rapid spreading, eye pain, or changes in vision, do not dismiss it as a simple recurrence and seek medical evaluation.
Symptoms and Differential Diagnosis
The priority of medical evaluation is determined by the texture of the scales, the affected areas, and the presence of pain or oozing
We examine the distribution on the face, ears, and chest, as well as symptoms suggestive of infection, rather than looking at the amount of dandruff alone.
| Visible or felt symptoms | What to check | Priority action |
|---|---|---|
| White scalp dandruff and itching | Possibility of mild scalp seborrheic dermatitis | Record distribution, recurrence, and response to shampoo |
| Yellow greasy scales and red or light-colored skin | Skin changes in typical sebum-rich areas | Check for accompanying symptoms on the face, ears, and chest |
| Recurring on eyebrows, sides of the nose, and behind the ears | Possibility of multi-area seborrheic dermatitis | Skin evaluation and treatment by area |
| Thick plaques, alopecia areata, blisters | Differential diagnosis of other scaly or contact rashes | Seek medical evaluation instead of self-diagnosing |
| Oozing, pus, pain, rapid redness | Possibility of infection | Prompt medical evaluation |

Seborrheic dermatitis is not a matter of hygiene, but a chronic disease where sebum skin barrier, and inflammatory responses fluctuate together. Rather than washing more vigorously as it recurs, one must examine the body condition and the factors that contribute to recurrence.

Seborrheic dermatitis: How to distinguish it from similar-looking skin diseases
First, rule out infection and eye symptoms
Check for oozing, pus, pain, fever, eye pain, and changes in vision.
Identify the texture and location of the scales
Record any white or yellow scales and changes in skin color on the scalp, eyebrows, sides of the nose, ears, and chest.
We also examine the recurrence interval of scaling and itching.
While maintaining dermatological treatment, we track changes in itching, nighttime sleep, and discomfort regarding appearance and work.
Why does it keep getting worse?
Reasons why seborrheic dermatitis persists or recurs
Distinguishing between oily scales and dry stinging
The priority of Korean herbal medicine treatment differs for those with a sticky, red scalp versus those with thinned facial skin that stings regardless of what is applied.
Identifying lifestyle causes for itching that occurs immediately after stress
We ask how the face and scalp change after overtime work, lack of sleep, alcohol consumption, or spicy foods, and only reflect conditions that actually recur in the prescription.
Checking sebum, heat, dryness, and the body's recovery capacity together
We determine the emphasis of Korean herbal medicine treatment by diagnosing whether oily redness and heat are predominant, whether the skin barrier is dried out and stinging after frequent cleansing, or whether dandruff and itching increase during lack of sleep, digestive discomfort, or fatigue.
Persistent erythema and burning sensations in the center of the face, along with fine blood vessels, are used to distinguish this from acne, which is centered around comedones. Only the skin surface is shown in close-up, excluding the eyes.
Things to prepare before your visit
What photos and records should I prepare before the medical evaluation?
Please prepare photos of your scalp, face, ears, and chest taken under the same lighting, information on the presence of scales, itching, or oozing, the timing of recurrence, and your response to shampoos, cosmetics, and treatments.
White dandruff may flake off
We examine fine scales falling on the shoulders, scalp itching, and changes in skin color along the hairline.
Yellow scales may also adhere oilily
Record whether thickened scales adhere to the scalp or around the ears along with a feeling of sebum.
How to distinguish wounds caused by scratching
Check whether blood or scabs formed after scratching, or if oozing or pus occurs spontaneously.
Changes to monitor during treatment
What changes should I monitor during treatment?
Recurring areas among the scalp, eyebrows, sides of the nose, and ears, and the texture of the scales
Please record when it started and how it has changed, including the dates. To make it easier to compare before and after, take photos of the same area from a similar distance and under similar lighting.
Names of shampoos, creams, and ointments, frequency of use, and the period of improvement
Please leave a brief note. Compare not only the visible changes but also whether your sleep, pain, and daily life have become less uncomfortable.
Changes in sebum, heat sensation, and itching after sleep, alcohol, or meals
Please also include the dates of any medications, ointments, or procedures you are currently using. This makes it easier to compare what led to improvement or worsening.
Redness in the center of the face and fine blood vessels that remain even when not triggered are different clues from temporary flushing. We check for rosacea along with papules, scaling, and eye symptoms.
When planning herbal medicine treatment
For seborrheic dermatitis, the direction of Korean herbal medicine treatment is determined based on the most prominent current symptoms
We do not repeatedly provide prescriptions to reduce sebum simply because there is a lot of dandruff. We differentiate whether the focus is on yellow, sticky scales and heat; whether redness concentrates in the face and scalp; whether the issue is a thin, stinging barrier after frequent cleansing; or whether it recurs after lack of sleep, digestive issues, or fatigue.
Pattern identification (Byeon-jeung) in Korean medicine is not about giving a different name to a disease. Multiple patterns can overlap in one person, and as the skin changes, for example, as oozing and heat decrease and dryness or cracking remain, the prescription is adjusted accordingly.
When yellow scales are sticky and the scalp feels hot
- Primary skin observations
- Check if yellow scales, sebum, and redness adhere stickily to the scalp, sides of the nose, eyebrows, and behind the ears.
- Overall body condition to check alongside skin
- Check if symptoms worsen after alcohol, oily foods, or late-night snacks, and if there is bloating or dry mouth.
- Primary considerations for herbal medicine prescription
- Focus on clearing heat and removing dampness to lower the heat and moisture rising to the skin surface and reduce the burden on the spleen and stomach.
When the face and scalp are red, burning, and itchy
- Primary skin observations
- Observe vivid redness and heat in the scalp, hairline, between the eyebrows, and the wings of the nose, as well as scales that fall off when scratched.
- Overall body condition to check alongside skin
- Ask about upper body heat, thirst, dry cough or nasal symptoms, and whether symptoms worsen in hot spaces.
- Primary considerations for herbal medicine prescription
- Adjust the balance of clearing the lungs and clearing heat to lower the heat concentrating upward and skin inflammation, while ensuring it does not cause excessive dryness.
When white scales and stinging are more prominent than oiliness
- Primary skin observations
- Observe if white, fine scales, tightness, stinging, or micro-cracks remain after excessive cleansing.
- Overall body condition to check alongside skin
- Check for accompanying dryness of the skin and mouth, fatigue, a feeling of coldness, and delayed wound healing.
- Primary considerations for herbal medicine prescription
- Rather than further suppressing sebum, focus on nourishing the blood, moisturizing dryness, and restoring the barrier to create skin that can withstand cleansing irritation.
When the scalp becomes itchy again after overtime work and stress
- Primary skin observations
- Observe if dandruff and itching suddenly increase rather than major inflammation, and if the face and scalp worsen alternately.
- Overall body condition to check alongside skin
- Ask if the timing of worsening overlaps with lack of sleep, tension, digestive discomfort, or afternoon fatigue.
- Primary considerations for herbal medicine prescription
- Adjust tension, digestion, and recovery capacity together to reduce the conditions that cause recurring sebum and heat reactions.
How is the herbal medicine prescription adjusted?
- First, distinguish between oily or dry
By distinguishing between yellow scales/heat and white scales/stinging, the balance between clearing heat/removing dampness and moisturizing dryness/barrier recovery is determined.
- Connect the scalp and face with lifestyle worsening factors
Verify the relationship between the movement of affected areas and the timing of shampooing, face washing, alcohol consumption, overtime work, and meals.
- We examine not only the amount of dandruff but also how long the comfortable state is maintained.
We check for nighttime itching, stinging after cleansing, the extent of redness, and whether the intervals between days requiring shampoo or ointment are becoming longer.
When should I consider Korean herbal medicine treatment?
- When scaling and redness return immediately after stopping antifungal shampoos or ointments, even if they had improved.
- When scalp itching and facial stinging make sleep, makeup, or wearing dark clothes burdensome.
- When there is a clear pattern of repeated worsening following stress, alcohol consumption, or lack of sleep.
What will be asked during the medical evaluation?
- Recurring areas among the scalp, eyebrows, sides of the nose, and ears, as well as the texture of the scaling.
- Names of shampoos, creams, and ointments used, frequency of use, and the duration of improvement.
- Changes in sebum, heat sensation, and itching after sleep, alcohol consumption, or meals.
Things to prepare before the consultationPlease prepare photos of your scalp, face, ears, and chest taken under the same lighting, and information on the presence of scaling, itching, or oozing, the timing of recurrence, and your response to shampoos, cosmetics, and treatments.
If pus, pain, or redness spreads rapidly, or if you have a fever, lesions inside the eyes or mouth, shortness of breath, or sudden facial swelling, please visit a dermatology clinic or seek emergency care first. After confirming that such urgent situations are not present, Baekrokdam provides herbal medicine treatment for chronic and recurring skin diseases.

Frequently Asked Questions about Seborrheic Dermatitis
What does seborrheic dermatitis dandruff look like?
Scaling on the scalp may appear as fine white flakes or as oily, yellowish scales that adhere to the skin.
Can seborrheic dermatitis occur on the face?
Scaling and skin color changes can recur in areas with high sebum production, such as the eyebrows, eyelids, creases beside the nose, and around the ears.
Is seborrheic dermatitis only itchy?
In addition to itching, you may experience stinging, burning, and irritation. Severe pain, oozing, or pus requires a check for infection.
If I have both scalp scaling and hair loss, is it seborrheic dermatitis?
Since there are other causes such as tinea, if you notice circular hair loss or broken hairs, do not self-diagnose and seek a dermatological evaluation.
What is the exact cause of seborrheic dermatitis?
A single cause has not been identified; it involves sebaceous gland activity, Malassezia yeast, the skin barrier, and individual inflammatory responses.
Is stress the cause?
While stress can trigger recurrence or worsening, it is not a disease caused solely by an individual's mindset.
Does it always occur if there is a lot of sebum?
Although common in areas with high sebum, the occurrence cannot be explained by the amount of sebum alone. The skin barrier and individual responses are also considered.
