Red Flags & When to Go In Person for Dandruff (Seborrheic Dermatitis)

Audience: adult

Dandruff, also known as seborrheic dermatitis, is a common skin condition that causes flaky, itchy scalp skin. It often appears as white or yellowish flakes and can sometimes affect other oily areas like the face or chest. While dandruff is usually mild and manageable with over-the-counter shampoos and good scalp care, certain signs mean you should see a healthcare provider in person. These include severe redness, swelling, pain, or if the flakes become thick and crusty. Also, if dandruff spreads beyond the scalp or does not improve with usual treatments, it’s important to get an in-person evaluation. Telemedicine can help assess mild dandruff and provide advice on treatment, but it cannot replace physical exams needed for more serious or unclear cases. Knowing when to seek in-person care helps ensure you get the right treatment and avoid complications.

Red flags — go in person / ER

• Severe redness, swelling, or pain on the scalp — seek urgent in-person care.
• Thick, crusty, or oozing patches on the scalp — may indicate infection requiring medical evaluation.
• Dandruff spreading beyond the scalp or not improving after several weeks of treatment — see a healthcare provider in person.

What telemedicine can do

• Assessment of mild dandruff symptoms via video or photos.
• Providing advice on over-the-counter treatments and scalp care.
• Determining if symptoms may require in-person evaluation.

What telemedicine cannot do

• Physical examination to diagnose severe or complicated skin conditions.
• Treatment of infections or severe inflammation needing prescription medications.
• Performing diagnostic tests like skin scrapings or biopsies.

FAQs

Can dandruff go away on its own?

Dandruff often improves with regular hair washing and use of anti-dandruff shampoos, but it may come and go over time. It usually does not go away completely without treatment.

Is dandruff contagious?

No, dandruff is not contagious. It is related to skin conditions and yeast that normally live on the skin.

Can diet affect dandruff?

While diet is not a direct cause, a healthy diet may support skin health. Some people find that reducing sugary or fatty foods helps, but evidence is limited.

When should I see a doctor in person for dandruff?

See a doctor if you have severe redness, swelling, pain, thick crusts, spreading rash, or if symptoms do not improve with treatment after several weeks.

Can telemedicine help with dandruff?

Telemedicine can help assess mild dandruff and provide treatment advice, but cannot replace in-person exams needed for severe or unclear cases.
