Treatments to help get rid of psoriasis on the scalp include:

    • Look for products such as shampoos that contain:
      • Salicylic acid which helps soften plaques and scales and remove scales from the skin
      • Coal tar or wood tar, which helps slow skin cell growth and reduce inflammation, itching, and scaling
      • Scale lifters (keratolytics) with an active ingredient of salicylic acid, lactic acid, urea, or phenol help loosen and remove scale, allowing medications to reach the psoriasis plaques
      • Anti-itch treatments such as calamine, hydrocortisone, camphor, diphenhydramine hydrochloride (HCl), benzocaine, and menthol (may increase irritation and dryness)
      • Aloe vera, jojoba, zinc pyrithione, and capsaicin may help moisturize, soothe, remove scale, or relieve itching 
      • Castederm may be used for inverse psoriasis to help dry moist plaques in the folds of the body
      • Bath solutions such as oil, oatmeal, Epsom salts or Dead Sea salts can help remove psoriasis scales and soothing itch
      • Coverings such as cellophane, plastic wrap, waterproof dressing, cotton socks, or a nylon suit may be applied over topical treatments which can help increased the effectiveness of some topical medications or moisturizers
  • Prescription topical treatments
  • Phototherapy (light therapy)
    • Ultraviolet light B (UVB): broad band and narrow band
    • Psoralen + UVA (PUVA
  • Systemic treatments
