Head Lice Facts: Eggs and nits are not the same thing: it is important to know the difference to eliminate an infestation. Eggs: developing lice that have not yet hatched; laid at root of hair to scalp; very difficult to see because color blends in with hair and because they are so small. Nits: empty eggshells left behind after the eggs have hatched; whitish in color and found further away from scalp (1/4 inch or more since hair has grown by the time eggs hatch). To completely eliminate lice you either need to kill the lice with a lice killing treatment or remove the lice mechanically and comb out the eggs. Nits need to be combed out for cosmetic reasons and because many schools require children to be nit free before they can go back to school. Both eggs and nits are bound to the hair with a glue-like substance making them hard to detach. Combing is the only way to remove them. Hair conditions and special gels can make the combing process faster and easier but nothing has been proven to dissolve the glue. A well designed combing system is the most important tool to use to remove all the eggs and nits. Only RID has a unique, 2 comb system for complete lice, egg and nit removal. Each comb is designed to provide the proper grip and angled motion to aid in the complete elimination of lice infestations. The short-pin comb is for lice and egg removal. The angle and short pins allow you to easily access the root of the hair where the lice and eggs are located. The narrow spacing between the teeth ensures that the lice and eggs do not slip through, and the rounded ends of the teeth make the comb gentle on the hair. The long-pin comb is for nit removal. The longer teeth are tapered so multiple hairs can be funneled through the teeth enabling you to comb out many nits at one time. Made from high quality stainless steel.
