Having a wound on your head that has lasted a year, causes itching and pain, and is associated with hair loss is concerning and needs careful evaluation. This could indicate an ongoing infection, inflammation, or a skin condition affecting the scalp.

• It is important to see a dermatologist (skin specialist) promptly for a thorough examination and possibly a biopsy or culture to determine the cause.
• Avoid scratching the area to prevent further damage or infection.
• Do not apply any new topical treatments without medical advice, especially since some products require prescriptions and may not be suitable without diagnosis.
• If you notice worsening pain, spreading redness, swelling, fever, or discharge, seek urgent medical attention.
