1. What Is Scalp Psoriasis?

Scalp psoriasis is a chronic autoimmune condition where the immune system triggers skin cells to build up too quickly. The result? Red, raised, scaly patches that can appear along the hairline, behind the ears, or even cover the entire scalp.

It’s not contagious—but it can be painful, itchy, and emotionally distressing for those living with it.

2. Scalp Psoriasis vs Dandruff: What’s the Difference?

Dandruff is typically caused by dry skin or an overgrowth of yeast and flakes off easily. Scalp psoriasis, on the other hand, creates thick patches of silvery-white scale over inflamed skin.

Key differences:

Feature Dandruff Scalp Psoriasis

Color of flakes White or yellowish Silvery white over red patches

Itching Mild to moderate Often severe

Skin inflammation Rare Common—skin appears bright red

Bleeding if picked Unlikely Possible

3. What Does Mild Scalp Psoriasis Look Like?

Early-stage or mild scalp psoriasis often shows up as:

Small, flaky patches near the hairline

Slight redness or irritation

White flakes mistaken for dandruff

Occasional itching

This stage may come and go and is often triggered by stress, cold weather, or harsh shampoos.

4. Moderate to Severe Scalp Psoriasis Symptoms

As the condition worsens, symptoms become more visible and uncomfortable:

Thick, crusty patches that feel rough to the touch

Silvery-white scale buildup over red or pink skin

Itching, burning, or soreness in affected areas

Dry scalp with cracking or bleeding when scratched

Hair loss (temporary, due to scratching or inflammation)

These patches can appear:

All over the scalp

Behind the ears

On the forehead/hairline

Down the back of the neck

5. Scalp Psoriasis Photos: What to Expect Visually

In real-world cases, scalp psoriasis may look like:

Dry, cracked terrain across the scalp

Red patches peeking through hair

“Frosted” scale buildup, like snowflakes stuck to the scalp

Thickened plaques that resemble scabs or crusts

Yellowish buildup in cases of overlapping seborrheic dermatitis

Photos online often depict severe cases—but your flare-up may be much milder in appearance. Always consult a dermatologist for diagnosis.

6. Other Signs to Watch For

Itching that worsens at night or after hair washing

Bleeding from scratching

Stress-related flares

Cracked skin behind ears or at base of neck

Flare-ups after new hair products or cold weather

Scalp psoriasis can also extend to the forehead or nape of the neck, often forming a clear border known as the psoriatic corona.

7. Common Triggers of Scalp Psoriasis

Scalp psoriasis isn’t random. Common triggers include:

Stress or anxiety

Seasonal changes (especially cold, dry winters)

Smoking or alcohol

Illness or infections

Harsh hair dyes or products

Hormonal shifts

Tracking your flare-ups can help identify and manage your personal triggers.

8. Treatment Options

Once diagnosed, scalp psoriasis can be managed through:

Medicated shampoos (coal tar, salicylic acid, ketoconazole)

Topical steroids (clobetasol, betamethasone)

Vitamin D creams (calcipotriene)

Phototherapy (UV light exposure under medical supervision)

Oral/injectable biologics for moderate to severe cases

Pro tip: Soften scales with coconut or olive oil before shampooing to reduce discomfort.

9. When to See a Doctor

See a dermatologist if:

You’ve had flaking for more than 3 weeks

OTC treatments don’t help

Flare-ups are painful or bleeding

You’re embarrassed or avoiding social situations

Patches extend beyond the scalp

A medical diagnosis ensures you’re not dealing with something more serious—or missing out on prescription-level relief.
