Folliculitis: Why Does the Headache Occur in the Head?

The main causes of headaches resulting from folliculitis of the scalp are as follows: 1. **Worsening bacterial infection**: Folliculitis is primarily caused by bacterial infection. When the infection worsens, it leads to local tissue edema and swelling, which can compress surrounding nerves, resulting in headache. 2. **Impaired scalp blood circulation**: Folliculitis may be accompanied by poor blood circulation in the scalp, affecting nutrient supply and waste elimination in scalp tissues, potentially triggering headaches. 3. **Scalp nerve reflex**: Folliculitis can stimulate nerve endings around the scalp, sending signals through the nervous system to the brain, causing the sensation of headache. 4. **Inflammatory response**: As an inflammation of the hair follicles, folliculitis can cause swelling in deeper layers of the scalp tissue, compressing nerves and leading to headaches. 5. **Psychological response**: The pain caused by folliculitis may lead to psychological tension and anxiety, which can further intensify the perception of headache.
