I'm a completely neurotic when nits hit town. Normally I go out and get the strongest formula in town and treat all heads in the house, clean all the bedding, boil all hairbrushes and hair paraphanalia. My eldest (8years) is Aspergic like (under dx at the moment) and goes bananas when using the formula or the nit comb. Being neurotic this doesn't stop me - nevertheless every week since the middle of August now I've found the nits again. We must have tried every formula in the country and gone through more bottles of hair conditioner than you would believe! I've also tried the new "wonder comb" that costs the earth. SHE STILL HAS NITS!!!! What the hell can I do.
