White Flakes and Itching? What You Need to Know About Scalp Psoriasis in Winter

During winter, many people notice white flakes appearing on their scalp. Most often, this is mistaken for dandruff or dry skin. However, in many cases, it can be a sign of scalp psoriasis, an inflammatory skin condition.

What is Psoriasis?

Psoriasis is a chronic inflammatory skin disorder caused by abnormal immune system activity. It causes the affected area to become red, itchy, and covered with thick, white, scaly skin.

Unlike ordinary dandruff, the scales in psoriasis are thicker and denser. Besides the scalp, psoriasis can appear on the forehead, around the ears, hands, feet, nails, and other parts of the body.

In scalp psoriasis, the flakes may resemble dandruff but do not improve with regular anti-dandruff shampoos.

Causes of Psoriasis

The exact cause of psoriasis is not fully understood, but major contributing factors include:

• Immune system issues: Abnormal immune responses cause skin cells to multiply rapidly.
• Genetic factors: Family history increases the risk of developing psoriasis.
• Environmental influences:
  • Dry winter weather
  • Seasonal changes
  • Stress or anxiety
• Lifestyle factors: Smoking or unhealthy habits can worsen the condition.

Symptoms of Scalp Psoriasis

It is important not to confuse psoriasis with regular dandruff. Key signs include:

• White or gray scaly skin:
  • Thicker and denser than dandruff
  • Easily comes off when scratched
• Redness and itching:
  • Red patches on the scalp
  • Intense itching compared to normal dandruff
• Spots on the forehead or around the ears:
  • Small white or red patches may appear
• Nail and hand/foot involvement:
  • Pitting, roughness, or minor pain
• Psoriatic arthritis (possible):
  • Joint pain, particularly in hands and feet, may accompany the skin condition

Treatment and Management of Psoriasis

Psoriasis does not typically improve with ordinary dandruff shampoos. Consulting a dermatologist is essential for proper treatment.

Main treatment options:

• Topical therapy (creams and ointments):
  • Corticosteroid creams or ointments
  • Shampoos containing salicylic acid
• Medication:
  • Oral or systemic medicines may be prescribed by a doctor
• Physical therapy:
  • Excimer laser treatment
  • UV-B light therapy

Lifestyle Changes:

• Maintain a healthy diet and proper nutrition
• Regular exercise and stress management
• Avoid scratching or massaging with oil on affected areas

Environmental and Seasonal Management:

• Control dryness during winter
• Maintain indoor humidity levels

Important Notes:

• Psoriasis is not contagious, but it is a chronic condition.
• If there is a family history, preventive measures are recommended.
• Seek medical advice if itching, redness, or nail problems appear.
