I’ve got 2 recommendations for getting rid of head lice:
1. The Nuvo Method. It’s a scientifically tested technique that suffocates the lice using non-toxic off the shelf cleansers. It’s easy to do, just time consuming.
2. The V-Comb Head Lice Comb. It’s a lice comb combined with a plug in vacuum. The filters let you see the nits and other stuff that you’re sucking up. Unlike a comb, you don’t have to worry about the nits falling back into the hair, so this is more efficient. The filters are supposed to be disposable, but I found that you can wash them with hot water and re-use them. Available from Amazon and other retailers.
