Pyrethrins/Permethrins - Natural pyrethrins were first introduced into the US in the 1980s as a less-toxic alternative to lice shampoos containing lindane (Kwell, etc.). A number of pyrethrin formulations are sold over the counter, such as Rid, Clear, A-200 as well as many private label brands with the same formula. Lice that are resistant to pyrethrins are also resistant to permethrin products like Nix and pyrethroids (synthetic pesticides having a chemical formula similar to natural pyrethrins). As a consequence, the entire pharmacological class is becoming less valuable. Common Sense Pest Control Quarterly (B.I.R.C.) Fall 1998 The marketing of permethrin in Israel started in 1991. The first reports of resistance were in 1993, a time equivalent to 40 generations of lice. Similarly, resistance was reported within four years of introduction in the countries of France, the Czech Republic and Great Britain.
CONCLUSION - As you can see throughout history, when one synthetic pesticide POISON fails to remain effective, another synthetic pesticide POISON is chosen and put into use. Without ever knowing their potential long-term health consequences, we simply substitute one synthetic pesticide POISON for another and hope that the head lice do not quickly develop a resistance. This never happens. Head lice have demonstrated time and time again that nature's "adapt and survive" adaptation will eventually help all pests to develop a resistance to that synthetic pesticide POISON as well. So, why continue to use/misuse dangerous and ineffective synthetic pesticide POISONS?

SAFE SOLUTIONS LICE R GONE(R) - One of the challenges to successfully treating someone with head lice is that you have two distinctly different problems you are trying to solve at the same time; remove the head lice and also remove the nits. Before Lice R Gone (R) was invented and patented, attempting to kill the head lice with pesticides andthen combing out the nits was the logical first step. After many applications, numerous generations of lice were exposed to the chemical creating "super lice" that could withstand future doses of these dangerous synthetic pesticide POISONS. The nits, however, were a more complex problem because these dangerous synthetic pesticide POISONS did not kill all of them and actually made the nits harder to remove. The surviving nits remained even more firmly glued to the hair and then began to hatch in 7-10 days. Then you had to start using/misusing these dangerous synthetic pesticide POISONS all over again. This is why the labels on these dangerous synthetic pesticide POISONS state that you have to use them at least now and then again 7 days later when the nits hatch. So you and your child now are exposed to at least twice the harmful pesticide exposures, twice the application times and twice the overall costs. Because of all the resistance some poor children are exposed to dangerous POISONS many, many times and still have their lice and nits!
With LICE R GONE(R), one single half ounce of this FDA registered shampoo gets rid of head lice and the nits in about ten minutes without combing. Lice R Gone (R) literally dissolves the protein nit glue that holds the nits to the hair shaft, allowing them to be easily rinsed away. The head lice and nits are safely and quickly rinsed off the head and down the drain in about 10 minutes. And best of all, there simply is no possibility of any type of resistance developing.
