Shraga18 – I’m sure you have tried all the remedies above by now and it still didn’t work. Oh and btw, they have electronic lice zappers that instantly kill lice and electronic combs that make combing much easier.
But if you did everything above and the lice isn’t killed – you need to get a prescription for Lindane (toxic to infants, lactating or pregnant women) or .5% Malathion. The lice is hardly ever resistant to these drugs.
