Combine the white vinegar and cool purified water in the spray bottle. Shake it for a minute to mix the solution. The vinegar neutralizes chemical burns.
Hold the spray bottle approximately 4 inches from the affected part of your scalp. Spray a fine mist over the chemical burn. This should immediately cleanse the area, while providing you with slight relief.
Pat the area dry with a clean, dry linen cloth.
Shake a can of Lanacane, or similar topical analgesic spray (sold in the first-aid sections of most stores). Hold the can 4 to 5 inches from the burn and spray the entire area. Repeat this process daily.
