Covering the head with a shower cap helps to prevent the oil from transferring to pillows and allows the heat of the scalp to enhance the oil's efficacy. While this mechanical action can be effective against the mobile adult lice, the same suffocating process does not reliably penetrate the hard shell of a nit to reach the developing embryo inside.
