What is Scalp Psoriasis?
Scalp Psoriasis is a chronic autoimmune condition that can be physically uncomfortable and emotionally distressing. Unlike simple dandruff, psoriasis causes red, inflamed patches covered in thick, silvery-white scales (plaques). It occurs when your immune system mistakenly speeds up skin cell turnover — instead of shedding invisible skin cells over weeks, your scalp produces them in days, causing them to pile up on the surface.
At Sussex Hair Clinic, Consultant Trichologist Shuna Hammocks understands that this condition is not just “skin deep.” It is often linked to internal inflammation and requires a specialist management plan to keep flare-ups under control.
Symptoms: identifying Scalp Psoriasis
Many patients visit us from Crawley, Horsham, and Tunbridge Wells after standard dandruff shampoos have failed. Psoriasis has distinct characteristics:
Silvery-White Scales
Thick crusts that can bleed if picked or scratched.
Red, Inflamed Patches
Often extending beyond the hairline onto the forehead, neck, or behind the ears.
Itching & Burning
A sensation of tightness or soreness that can be severe.
Temporary Hair Shedding
Psoriasis doesn’t kill the follicle, but removing thick scales can pull out hair.
What causes Scalp Psoriasis (the Sussex trigger factors)
The exact cause is complex, but it is fundamentally an immune system error. Shuna Hammocks notes that many patients with Psoriasis also suffer from thyroid issues, arthritis, or inflammatory bowel conditions. In our Sussex clinic, we often see specific triggers that spark a flare-up: the fast-paced lifestyle of the South East and commuting to London; a lack of sunlight and Vitamin D during British winters; and a history of high fevers or severe viruses, which can trigger the body to “turn on itself,” sometimes years after the illness occurred.
How Shuna Hammocks treats Scalp Psoriasis
“I generally avoid suggesting steroid creams,” says Shuna. “While they work quickly, they thin the skin harshly over time.” Instead, Shuna offers a long-term management approach that you can maintain safely:
Descaling & scalp lotions
We use specific keratolytic treatments to gently lift the thick plaques without damaging the hair or skin, then relieve the “tight” feeling that follows with lotions that prevent the skin from cracking.
Diet & medicated shampoos
Identifying inflammatory foods to avoid and supplements to support your immune system, alongside the exact medicated shampoo formulation that suits your scale thickness and hair texture.
Frequently asked questions about Scalp Psoriasis
Can scalp psoriasis cause permanent hair loss?
Generally, no. Psoriasis is not a scarring alopecia. However, aggressive scratching or harsh removal of the plaques can pull hair out. Once the inflammation is managed by Shuna, the hair typically regrows.
Is it contagious?
Absolutely not. You cannot catch psoriasis from someone else, nor can you pass it on. It is an internal genetic and autoimmune condition.
Should I see a GP or a Trichologist?
While GPs can prescribe medication, they rarely have the time to investigate your diet, lifestyle, or apply therapeutic treatments to remove scales safely. Shuna Hammocks provides a holistic, detailed investigation into your specific triggers.
