Head Psoriasis Spreading to the Back

What might be the reasons for the head psoriasis spreading to the back?

Psoriasis is a common chronic skin disease that often presents as red patches covered with silvery scales. It may affect the scalp, hands, feet, legs, lumbosacral area, buttocks, and other areas, with the scalp being the most common site of involvement. Therefore, the possible reasons for psoriasis spreading from the head to the back include:

1. Disease progression: Psoriasis is a chronic disease, and symptoms and spread usually worsen rather than improve. If there are no relief measures, psoriasis on the head may spread to other parts of the body, including the back.

2. Skin friction: Psoriasis can cause the skin to become dry, flaky, or scaly. These surface problems can cause friction between the head and clothing or other objects, further spreading to the back.

3. Scalp itching: The scalp affected by psoriasis is often particularly itchy, and when the patient scratches the scalp, dandruff is easily shed onto other parts of the body.

4. Improper treatment: Long-term use of certain chemical or drug treatments for psoriasis may damage the skin, and this could lead to psoriasis on the head also spreading to other areas of the body.

How can head psoriasis be prevented from spreading to the back?

1. Take effective treatment: Early diagnosis and timely treatment are effective methods to reduce symptoms. Treatment for psoriasis can be divided into local treatment, phototherapy, oral medication, and so on. Specific treatment plans can be consulted with the doctor's advice.

2. Pay attention to moisturizing: Applying moisturizing lotion, glycerin, or other moisturizers to the skin affected by psoriasis can help alleviate symptoms, prevent skin dryness and roughness, and avoid dandruff from spreading to other parts of the body.

3. Avoid skin friction: Try to reduce friction between the scalp and clothing or other objects, and choose breathable clothing.

4. Do not scratch the scalp excessively: Try to avoid excessive scratching of the scalp to prevent dandruff from falling onto other parts of the body and causing new symptoms.
