Nit treatment usually consists of mechanical removal of the nit from the hair shaft by either pulling with one’s fingernails or with a good nit comb. Currently, nit treatment is limited to mechanical removal due to the chemical composition of the glue that lice use to attach the nit to the hair follicle. This glue consists of four proteins very similar in structure to actual human hair, therefore any chemical solvent capable of breaking down the glue is going to also be extremely damaging to hair and even skin; however, certain essential oils such as ones used in Lice Off, have been shown to effectively kill nits without toxic and potentially harmful chemicals.
