Hello, and thank you for your question. It’s understandable to be concerned about hair loss following a head injury. Here are some insights into your situation: Trauma-Induced Hair Loss: Hair loss following a head injury can occur due to trauma to the hair follicles. This type of hair loss is usually temporary and is known as "traumatic alopecia." Healing Process: The scalp is highly vascular, which generally promotes good healing. If the injury was minor and there is no significant scarring, the hair is likely to grow back as the scalp heals. Signs of Permanent Damage: If the injury caused a deep wound or significant scarring, there might be a risk of permanent hair loss in that area. However, this is less common with minor injuries. Care and Treatment: To aid the healing process, keep the area clean and avoid any further trauma. Topical treatments, such as mild antiseptics or antibiotic ointments, can help prevent infection. If there is inflammation, over-the-counter anti-inflammatory medications might be beneficial. When to See a Doctor: If you notice persistent baldness, signs of infection (redness, swelling, pus), or if the area is not healing as expected, it’s important to consult with a dermatologist or healthcare provider for a thorough evaluation and appropriate treatment. In most cases, hair should regrow once the scalp heals. Monitoring the area and maintaining good scalp hygiene will support the natural healing process. Warm regards,
