Hi Rickman
LOL don't worry, I frequently get one or two from my 'lousy' kids! (They are not really lousy but kids in their class are all the time, poor things!)
Don't go down the chemical route.. not worth it.. just dump a load of conditioner on your head and go through it with a nit comb lots of times. If you do this every time you wash it, you can stay on top of the problem like this. I do this for DD and I when nits are really rife at various times a year. The chemical de-louser stuff is not really recommended for kids anymore and most docs won't prescibe it.
Also, use tea tree & mint shampoo and condtioner all the time.. it discourages the little sods!
