I'm desperate! I just got a call from my SIL saying her son has lice We stayed with them this weekend and now I'm freaking out that my 2 youngest are infested. I'm scratching everywhere and washing EVERYTHING! They are in school now so I can't check them until they get home. Do any of you have any natural treatments that have worked for you? I've read a few things like mayo and olive oil but there are conflicting reports. I know you shouldn't use the lice treatment shampoo until they actually have them but if I can prevent them or stop them before it gets worse I'm all for it. TIA for anything you can share with me
