Itching and hair loss on the lower scalp can be caused by several factors such as scalp infections, dandruff, or irritation. To help manage this, you can gently cleanse your scalp with a mild shampoo, avoid harsh hair products, and keep the area moisturized.

• Consider using an anti-dandruff shampoo containing ingredients like ketoconazole or zinc pyrithione if dandruff is suspected.
• Avoid scratching to prevent further irritation or infection.
• Nutritional supplements like Biocod-MX, which contains vitamins and minerals, may support overall hair and scalp health, but it’s best to use them under medical advice.
