Yes, scalp psoriasis can spread to other parts of the body. Although it often starts on the scalp, if not properly managed, the lesions can extend to the forehead, neck, behind the ears, and even the trunk or limbs. It is recommended to consult a doctor promptly and control the progression of the condition through proper care.
This can be understood from the following two aspects:
1. Potential for Spread: Psoriasis is a chronic skin condition that is related to the immune system. When erythema and silvery-white scales appear on the scalp, the original lesions may expand if scratched, irritated, or under stress or infection, or new similar lesions may appear on other parts of the body. This is not inevitable, but it is indeed something that some patients will experience.
2. Manifestations of Spread: Spreading is not a sudden, all-over process, but rather a gradual one. It commonly starts around the hairline and spreads to the forehead and behind the ears; sometimes, well-defined red patches covered with dry scales appear on the elbows, knees, or back. Observing and recording skin changes helps doctors diagnose the condition.
To reduce the risk of spread and manage the condition effectively, you can take the following precautions: First, avoid vigorous scratching or hot washing of the scalp; gently cleanse and use topical medications as prescribed by your doctor. Second, keep the skin moisturized and use suitable moisturizing products to relieve dryness. Finally, maintain a regular sleep schedule and reduce stress, as emotional fluctuations can also affect the condition. If you notice a significant expansion of the lesions or the appearance of new rashes, please consult a doctor promptly so that a professional can adjust the treatment plan.
