Psoriasis on the forehead can be improved through proper treatment and daily care. It is recommended to consult a dermatologist first to choose a gentle topical ointment, phototherapy, or oral medication based on the specific situation, and to avoid irritating the skin.

Specifically, we can start from the following aspects:

1. **Seek medical attention promptly for diagnosis:** Psoriasis requires professional diagnosis. Doctors will recommend appropriate treatment plans based on the severity of the lesions on the forehead, such as using ointments containing vitamin D or low-concentration hormones to help reduce erythema and scaling.
2. **Maintain Gentle Care:** Choose gentle cleansing products for your daily routine and avoid rubbing your forehead vigorously. Keep your skin moisturized by applying a doctor-approved moisturizer to help relieve dryness and discomfort.
3. **Reduce external stimuli:** Try to avoid sun exposure, cold, or friction on the forehead. Maintain a regular sleep schedule and reduce mental stress, as these factors may affect symptom recurrence.
Regularly observe changes in your skin. If symptoms worsen or new problems arise during treatment, promptly return for a follow-up appointment to adjust the treatment plan. With patient care and scientific treatment, the symptoms of forehead psoriasis can usually be relieved.
