Treatment Options:

  1. Topical Treatments: Medicated shampoos, corticosteroids, and keratolytic agents can help manage scalp psoriasis symptoms effectively.
  2. Phototherapy: Light therapy, also known as phototherapy, involves exposing the affected scalp to ultraviolet light to reduce inflammation and promote healing.
  3. Systemic Therapies: In severe cases where topical treatments and phototherapy are ineffective, systemic treatments such as biologics or oral medications may be prescribed to target the underlying immune response.


Scalp psoriasis is a challenging condition that not only affects the physical health of individuals but also impacts their emotional well-being.
