What Is Scalp Psoriasis?
Scalp psoriasis is a chronic inflammatory skin condition that affects the scalp, causing red, raised patches covered with silvery-white scales. It affects approximately 2–3% of the UK population and can range from mild flaking to severe crusting that extends beyond the hairline.
Unlike dandruff, which is caused by a fungal organism, scalp psoriasis is an autoimmune condition in which the immune system causes skin cells to grow too quickly. The excess cells pile up on the surface, forming the characteristic thick plaques.
Key fact: Scalp psoriasis is not caused by poor hygiene. It is an autoimmune condition and cannot be passed from person to person.

Symptoms and How It Differs from Dandruff
The key symptoms of scalp psoriasis are clearly demarcated red plaques, thick silvery or white scales, persistent itching, and a dry scalp that may bleed when scratched. The plaques often extend just beyond the hairline onto the forehead, behind the ears, or onto the back of the neck.
Dandruff produces fine, greasy-looking flakes and is usually confined to the scalp. Scalp psoriasis produces thicker, drier scales and frequently causes more intense itching. If over-the-counter antifungal shampoos do not resolve your symptoms within six weeks, a clinical assessment is recommended. See our guide: Dandruff or Scalp Psoriasis: How to Tell the Difference.
Scalp Psoriasis Flare-Up Triggers
While scalp psoriasis has a genetic basis, flares are typically precipitated by environmental triggers:
- Stress — psychological stress is one of the most consistent triggers; stress management can meaningfully reduce flare frequency
- Streptococcal infections — throat infections frequently trigger or worsen scalp psoriasis
- Certain medications — beta-blockers, lithium, antimalarials, and ACE inhibitors can precipitate or worsen psoriasis
- Skin trauma (Köbner phenomenon) — new plaques can develop at sites of scratching, cuts, or other skin injury
- Alcohol — excessive consumption is associated with more severe psoriasis and may reduce treatment effectiveness
- Smoking — a significant risk factor for more severe disease and poor treatment response
Treatment Options in the UK
On the NHS, scalp psoriasis is typically managed with potent topical corticosteroids, vitamin D analogues, or combination products such as Dovobet gel. For severe cases, phototherapy or systemic treatments including methotrexate or biologics may be considered.
Online treatment options allow faster access to prescription scalp psoriasis treatments without a long wait for a GP appointment.
