What triggers seborrheic dermatitis?

Seborrheic dermatitis is triggered by an overgrowth of Malassezia yeast on the skin, stress, cold and dry weather, hormonal changes, and certain medications. Oily skin, weakened immunity, and harsh hair products can also worsen flare-ups. Using a targeted antifungal shampoo like RoyceDerm helps calm the scalp environment where these triggers take hold.

How do you get rid of seborrheic dermatitis?

To get rid of seborrheic dermatitis, wash affected areas with a medicated antifungal shampoo, leave the lather on for 3-5 minutes, and use consistently for 2-4 weeks. Follow up with a gentle, pH-balanced conditioner to restore the scalp barrier. RoyceDerm Seborrheic Dermatitis & Psoriasis Shampoo is formulated specifically for this routine.

What is the root cause of seborrheic dermatitis?

The root cause of seborrheic dermatitis is a reaction to Malassezia yeast combined with excess oil production and immune system dysregulation. Genetics, stress, and environmental factors also contribute. Because it is not caused by poor hygiene, regular shampoo will not resolve it — a targeted antifungal formula is needed.

What is seborrheic dermatitis mistaken for?

Seborrheic dermatitis is often mistaken for dandruff, scalp psoriasis, eczema, contact dermatitis, or rosacea. The key difference is that seborrheic dermatitis produces greasy yellow scales in oil-rich areas like the scalp, eyebrows, and sides of the nose. A dermatologist can confirm the diagnosis if symptoms persist.

Can seborrheic dermatitis ever go away?

Seborrheic dermatitis can go into remission but rarely goes away permanently, as it is a chronic and recurring condition. Most people experience flare-ups triggered by stress, weather, or hormonal shifts throughout life. Regular use of an antifungal shampoo helps extend symptom-free periods and reduce flare-up severity.

What vitamin deficiency causes seborrheic dermatitis?

Deficiencies in biotin (vitamin B7), zinc, riboflavin (B2), pyridoxine (B6), and niacin (B3) have been linked to seborrheic dermatitis. Low vitamin D levels may also contribute to flare-ups. While supplements can support skin health, they do not replace topical treatment with a medicated shampoo.

What happens if you leave seborrheic dermatitis untreated?

If left untreated, seborrheic dermatitis typically worsens — itching intensifies, flaking spreads, and the inflamed scalp becomes vulnerable to secondary bacterial or fungal infection. Chronic scratching can also cause temporary hair thinning. Starting an antifungal shampoo early prevents these complications.

What are the red flags of seborrheic dermatitis?

Red flags for seborrheic dermatitis include widespread oozing, severe pain, fever, pus-filled sores, sudden hair loss, or symptoms spreading rapidly beyond the scalp. These signs suggest secondary infection or a different underlying condition and require a dermatologist's evaluation.

What foods should you avoid with seborrheic dermatitis?

Avoid sugar, refined carbohydrates, alcohol, fried foods, and dairy if you have seborrheic dermatitis, as they can trigger inflammation and worsen flare-ups. Foods high in omega-3s, zinc, and probiotics — like salmon, nuts, and yogurt alternatives — may help support healthier skin.

Who It’s For

Designed for dry, itchy-feeling and flake-prone scalps affected by visible flakes, excess oil, or recurring buildup.

What Makes It Different

Why Consistency Matters

Thorough Cleansing: Massage gently into the wet scalp and leave on for the time directed on the product label before rinsing thoroughly.

Routine Care: Consistent cleansing helps manage excess oil, visible flakes, and recurring scalp buildup.

This really works!

I have been suffering from recurring dandruff in the back of my scalp for 3 years and this product along with the cream helped me in 3 days! I never write reviews, but if I could help someone who suffered as long as I have, I say try it and I hope it works for you as fast as it worked for me! First two pictures was before. The last two pictures was 3 days after use of both the shampoo and the cream. By the next day, my scalp was normal but I used for 5 more days after to make sure it doesn’t recur.….

Does exactly what it says !

This soap actually works. After months of trying prescription creams and dozens of other “miracle cures” which just made it worse. I was sceptical of the products claims but decided to try it as I was desperate for a cure. I am so happy that within a week my symptoms had almost disappeared and after the second week all clear. Amazing….

“I rarely ever leave reviews, but this shampoo (& conditioner) are worth it today! I work in a hot, dirty environment with my sweaty hair tucked under a hat all day.

FAQs

Got questions? We’ve got answer...

What is this shampoo designed for?

This shampoo is designed for dry, itchy-feeling and flake-prone scalps. It helps cleanse excess oil, visible flakes, and recurring buildup while supporting scalp moisture and comfort.

Why must I leave the lather on for 3 to 5 minutes?

This is a critical step for clinical efficacy. Because psoriasis and dermatitis often involve a thickened scalp barrier, our high-potency botanical extracts require a few minutes of contact time to penetrate deep into the follicles and scales. Skipping this step may reduce the treatment's effectiveness.

How often should I use it?

Follow the directions on the product label. Appropriate frequency may vary depending on your scalp, hair type, and other products in your routine.

How long should I leave the shampoo on?

Massage the shampoo gently into the wet scalp and leave it on for the time directed on the product label before rinsing thoroughly.

Will this dry out my hair like other medicated shampoos?

No. Unlike traditional coal tar or high-sulfate treatments that leave hair feeling like "straw," our shampoo is pH-balanced and moisture-optimized. It treats the scalp aggressively while leaving your hair soft, manageable, and hydrated.

Should I continue using it once my symptoms have cleared?

Chronic conditions like dermatitis and psoriasis are often cyclical. To prevent "rebound" symptoms, we suggest using it once a week as a preventative measure. This helps maintain a healthy scalp microbiome and keeps the skin barrier resilient against environmental triggers.

How quickly will I notice a difference?

Results and timing vary by individual. Consistent use may gradually help improve scalp comfort and the appearance of visible flakes and buildup.

Can I use it with other RoyceDerm products?

Compatible RoyceDerm products may be used as part of the same routine. Follow each product’s directions separately and avoid combining active ingredients unless the labels permit it.
