How to Treat a Scalp Wound: First Aid Steps

A scalp wound can be alarming because the head is highly vascular, meaning it has many blood vessels close to the skin’s surface. This causes even small cuts to bleed profusely, often making the injury appear far worse than it actually is. A proper and immediate response is necessary to control blood loss and prevent infection or complications. Treatment involves assessing the severity of the injury, controlling the bleeding, cleaning the wound, and protecting it as it heals. This sequential approach ensures minor wounds are managed effectively while recognizing when professional medical intervention is required.

Identifying When to Seek Emergency Care

Before attempting at-home care, assess the injury for signs requiring immediate medical attention. A wound that continues to bleed heavily after 10 to 15 minutes of firm, continuous pressure should prompt a visit to the emergency room. Lacerations that are very deep (where the skull bone or fatty tissue is visible) or that have jagged edges that gape open likely require stitches or specialized closure.

An injury caused by high-impact trauma, such as a fall or high-speed object, may indicate a potential skull fracture or concussion. Look for neurological symptoms that signal a serious head injury, including loss of consciousness, severe or worsening headache, confusion, slurred speech, or repeated vomiting. If a foreign object, such as glass or metal, is embedded in the wound, it should not be removed at home, and the person should seek immediate care.

Stopping Bleeding and Initial Cleaning

For wounds deemed safe for home care, the immediate priority is controlling blood loss. The scalp’s high vascularity means bleeding can be dramatic. Apply firm, steady pressure directly onto the wound using a clean cloth, sterile gauze, or the cleanest material available.

Maintain this pressure uninterrupted for a full 10 to 15 minutes, resisting the urge to check the wound prematurely, as this can dislodge any forming clots. If the cloth becomes saturated with blood, place a fresh piece of material directly over the soiled one instead of removing the original dressing. Once the bleeding has slowed or stopped, the next step is thorough but gentle cleaning to prevent infection.

Use lukewarm running water and a mild soap to wash the wound and the surrounding skin. This rinses away dirt, debris, and dried blood. Avoid harsh agents like hydrogen peroxide or alcohol, which can damage healthy tissue and slow healing. If hair obscures the wound, carefully trim it around the edges to allow for better cleaning and dressing, but avoid dry-shaving the area, which can cause irritation.

Dressing the Wound and Monitoring for Complications

After the wound is clean, apply an antiseptic ointment, such as an antibiotic cream, in a thin layer to the laceration. The wound must then be covered with a sterile, non-stick dressing to protect it from contamination and further trauma. Securing a dressing on the curved, hair-covered scalp can be challenging, but medical tape or a conforming head wrap can help hold the gauze firmly in place.

The dressing should be changed daily, or immediately if it becomes wet or soiled. Monitoring the wound for signs of infection is necessary throughout the healing process. Symptoms suggesting a localized infection include increased redness, swelling, warmth around the wound edges, throbbing pain, or the presence of pus or foul-smelling drainage.

A fever or red streaks extending away from the wound are signs the infection may be spreading, and medical consultation is necessary. If the injury was caused by a dirty or rusty object, follow up with a healthcare provider to ensure tetanus immunization is current. Cuts that fail to show signs of improvement within a few days should also be evaluated by a professional.
