Vaseline can be used in a similar way as olive oil. Take the Vaseline and completely cover your scalp and hair with it. Then, put a shower cap or plastic bad over your scalp and leave the Vaseline on for between 12 and 24 hours. When you take off the cap, shampoo your hair without water, to break down the Vaseline, so that it’s easier to rinse out. Then wash your hair as normal, dry, and comb with a lice-removing comb. Be sure to regularly rinse this comb before you use it again – and be sure to keep combing for the next few days. And, at night, wear a shower cap – just in case there are some lice eggs lingering around your bed sheets that might get back in your hair.
