You'll usually post them on the areas you shave, tweeze, or wax. If you spot an ingrown hair, it's important not to be too aggressive and cause further irritation. Apply hydrating lotion to keep the skin moist, avoid tight clothing and synthetic fabrics, and exfoliate the area to help dissolve any dead skin to help loosen the hair and prevent new ingrowns from forming.
