Scalp Disorders
Psoriasis of the scalp.
Psoriasis is a chronic, immune-mediated condition in which skin cells renew too quickly and build up into thick, scaly patches. The scalp is one of the most commonly affected areas.

Understanding it
About scalp psoriasis
Scalp psoriasis usually appears as raised, well-defined red patches covered with silvery-white scales. It may extend beyond the hairline onto the forehead, neck or behind the ears, and can be itchy or sore.
Psoriasis tends to come and go in flares and is not contagious. Diagnosis and medical treatment are managed by a dermatologist; gentle, consistent scalp care can support comfort alongside that treatment.
Common causes
- An overactive immune response that speeds up skin cell turnover
- Genetics — it often runs in families
- Triggers such as stress, infections, skin injury or cold, dry weather
- Some medications

Managing it
Approaches that may help.
Dermatology treatment
Options include medicated topical treatments, light therapy and, for moderate to severe psoriasis, systemic or biologic medicines prescribed by a dermatologist.
Gentle scale care
Softening scales with appropriate products is gentler than picking or forcefully removing them, which can worsen symptoms.
Know your triggers
Managing stress and protecting the skin may help reduce flares.
Comfort between flares
A gentle, suitable routine supports scalp comfort alongside medical care.
When to see a physician
Please see a dermatologist for diagnosis and treatment. When medical care is involved, we collaborate with your physician.

Frequently asked questions
Your questions, answered.
We do not diagnose medical conditions; when medical care is involved, we collaborate with your physician.
How is psoriasis different from dandruff?
Psoriasis usually causes thicker, silvery scales on well-defined red patches that may extend beyond the hairline, while dandruff causes finer, looser flakes.
Can psoriasis cause hair loss?
Heavy scaling and scratching can cause temporary shedding in affected areas. Hair usually regrows as the skin settles.
Is psoriasis contagious?
No. Psoriasis is not contagious.
Can CRLAB treat psoriasis?
No. Psoriasis is treated by a dermatologist. We can support scalp comfort and care alongside that treatment.
