Understanding Why Dandruff Happens
The scalp constantly sheds dead skin cells — a normal process that is invisible under healthy conditions. Dandruff occurs when this renewal accelerates, producing clumps of visible flakes. The primary driver in most cases is Malassezia globosa, a yeast naturally present on the scalp. When it overgrows, it breaks down scalp oils into irritating byproducts that trigger an inflammatory response and accelerate shedding.
Scalp psoriasis, by contrast, is an autoimmune condition that causes thick, silvery plaques — not related to Malassezia but requiring its own targeted treatment approach.
Key point: Dandruff and scalp psoriasis can look similar but require different treatments. If standard anti-dandruff shampoos have not helped after 6 weeks, a clinical assessment may identify whether psoriasis or another condition is the cause.
Over-the-Counter Options
For mild-to-moderate dandruff, a high-quality anti-dandruff shampoo is usually the most effective first step. Key active ingredients to look for:
- Zinc pyrithione — antifungal and antibacterial; good for regular maintenance
- Selenium sulphide — highly effective at reducing Malassezia and slowing cell turnover
- Ketoconazole 1% — OTC antifungal; upgrade to 2% prescription formula for stubborn cases
- Coal tar + salicylic acid — removes thick scales and slows skin cell production
- Piroctone olamine — well-tolerated antifungal suitable for sensitive scalps

Choosing the Right Treatment
| Condition | First-Line Treatment | If No Improvement |
|---|---|---|
| Mild dandruff | OTC anti-dandruff shampoo (zinc pyrithione, selenium sulphide) | Nizoral 2% (ketoconazole) |
| Moderate dandruff / seborrhoeic dermatitis | Nizoral 2% shampoo | Betacap or Betnovate scalp application |
| Scalp psoriasis (mild-moderate) | Betacap scalp application | Etrivex shampoo or Dovobet gel |
| Stubborn thick scaling (psoriasis) | Cocois ointment (softening) | + corticosteroid application |
When to seek urgent care: Seek prompt medical attention if your scalp condition spreads rapidly, develops signs of infection (pus, hot skin, severe pain), or is accompanied by joint pain or widespread skin involvement.

Start Consultation →Frequently Asked Questions
What dandruff treatments are available from Access Doctor?
Access Doctor offers a range of medicated scalp treatments including Nizoral (ketoconazole 2%) shampoo, Betacap scalp application, Betnovate scalp application, Etrivex shampoo (clobetasol), Cocois ointment, and Dovobet gel, all available following a GPhC-regulated online consultation.
Do I need a prescription for dandruff shampoo?
Over-the-counter shampoos (such as 1% ketoconazole or zinc pyrithione formulations) do not require a prescription. However, stronger treatments — including 2% ketoconazole shampoo, Betacap, Betnovate, and Etrivex — are prescription-only and require a clinical consultation.
What is the difference between dandruff and scalp psoriasis?
Dandruff produces fine, white or grey flakes and is most commonly caused by Malassezia yeast overgrowth or seborrhoeic dermatitis. Scalp psoriasis produces thicker, silvery-scaled red plaques and is caused by an autoimmune response. The two conditions may look similar but require different treatments.
Can dandruff cause hair loss?
Dandruff itself does not directly cause hair loss. However, persistent inflammation and scratching can damage the scalp and temporarily weaken hair follicles. Treating the underlying scalp condition promptly reduces this risk.
