Complete with detangling teeth to help unlock knots, the Nitwits Head Lice Comb has stainless steel removal teeth, a 5 x magnifying glass to help locate those nasty nits and a long comfy grip handleNit combs have been specifically designed to accommodate the size of the head lice eggs, detach and remove them from the hair shaft. Nit combs have teeth that are fine enough to remove nits. Nits, the head lice eggs, are between 0.5 millimeters and 4 millimeters long which makes using a normal comb to remove lice almost impossible as the teeth are too far apart to hold the eggs as they are being removed.
As the size of this pesky parasite is quite small (Nymph ? between 1 and 2 millimeters and a Louse between 2 and 3 millimeters) try using a magnifying glass to help locate those hidden in behind the ears and towards to back of the neck.
Most eggs will detach from the hair shaft quite easily, however, you may find some are a little bit harder to remove. The egg is actually secured to the hair shaft by a glue-like substance the female louse secretes after she has laid the egg which can make removing nits (head lice eggs) difficult. In this case you can try to use your fingernails to loosen the attachment and then return to the nit combs.
NitWits have specially designed a nit comb (NitWits Head Lice Comb) which has been laboratory tested by the Insect Control & Research Inc. It is an all in one comb with detangling teeth to help remove knots, fine metal teeth to remove the head lice and their eggs plus a 5 x magnifying glass to help detect the lice and eggs.
