6. Pyrethrin Products
Pyrethrin-based products are some of the best science-based treatments out there when it comes to lice infestations. In fact, in years past, this was the accepted treatment that would be recommended by your doctor if you went to him or her and asked what you should use in the case of a lice infestation.
But the problem with these products is that they are no longer as strong as they used to be. Because of tighter FDA regulations and safety concerns, the potency of these products has gone way down. That means that it may not be as effective as you would like.
You have to follow the directions carefully on the current medication label to ensure that you kill all of the lice and their babies. These products come in the form of creams, lotions, and shampoos, and all have their own directions.
