Dandruff or scalp psoriasis? Solve the mystery before buying a shampoo

CHENNAI: Itching and flaking of the scalp are common, but they can indicate two very different conditions: dandruff or scalp psoriasis. Misdiagnosing these conditions can lead to ineffective treatment. Understanding the differences and seeking the right approach is key to resolving the problem effectively.

What Causes Dandruff and Scalp Psoriasis?

Dandruff: Caused by a fungal infection, dandruff results in greasy, yellowish flakes. It thrives on oily scalps and is often triggered by factors like stress, improper hair care, or weather changes.

Scalp Psoriasis: An autoimmune condition, psoriasis causes the immune system to speed up skin cell production. This leads to thick, silvery-white plaques that may itch or cause redness. It can also spread to areas beyond the scalp, such as the forehead, neck, and ears.

Symptoms of Dandruff:

- Fine, loose flakes that are white or yellowish.

- Typically worsens with an oily scalp.

- Often accompanied by mild itching but rarely causes redness or irritation.

- Responds well to over-the-counter dandruff shampoos.

Symptoms of Scalp Psoriasis:

- Thick, scaly plaques that are often silvery or whitish.

- Severe itching and possible redness or soreness.

- Often extends beyond the hairline and may involve other parts of the body.

- Does not improve with regular dandruff shampoos.

Key Differences to Note

Scalp Condition: Dandruff is more likely with an oily scalp, while scalp psoriasis is often linked to dryness.

Treatment Response: If dandruff shampoos fail to improve symptoms, it may indicate scalp psoriasis.

Spread: Unlike dandruff, scalp psoriasis can extend to areas outside the scalp, such as the back of the neck or behind the ears.

When to Consult a Professional

If symptoms persist despite using dandruff shampoos, consult a dermatologist.

They can confirm the diagnosis through a scalp examination and recommend effective treatments such as medicated shampoos, topical steroids, or systemic medications for psoriasis.

Why Early Diagnosis Matters

Delaying the right treatment can worsen symptoms, especially for scalp psoriasis.

Ignoring the condition may lead to chronic irritation, redness, and even hair loss in severe cases.

Final Advice

Don’t rely on guesswork when choosing a shampoo. Identify whether it’s dandruff or scalp psoriasis to ensure you use the correct treatment. If you’re unsure, always seek professional advice to achieve lasting relief.
