Some embodiments include a nit (louse egg) detection plate that provides a surface against which irregularities of a hair of a person are more apparent to a viewer than without the detection plate. The detection plate may also include a serrated edge that is operable to separate hairs of the person for viewing over the detection plate. Other embodiments provide a method for using the detection plate to detect and remove nits from hairs of a person. The method may include placing a thin layer of hair of a person over the detection plate, detecting nits by viewing the hairs against a backdrop provided by the detection plate, and removing any detected nits. ## Claims ### Claim 1 A method for treating a head lice infestation in a person, the method comprising: placing multiple head hairs of the person in front of a detection plate located adjacent to the head of the patient, the detection plate providing a contrasting background against which irregularities of a hair are more apparent to a viewer than without the detection plate; viewing the multiple hairs against the detection plate; detecting a louse egg sac attached to one of the multiple hairs; and removing the louse egg sac, wherein placing the multiple hairs of the person includes positioning the multiple hairs between eyes of a viewer and the detection plate, such that the detection plate provides a background against which the viewer can examine the multiple hairs for the presence of lice eggs. ### Claim 2 (depends on 1) The method of claim 1, the detection plate including: a serrated edge configured to separate hairs of the person. ### Claim 3 (depends on 2) The method of claim 2 wherein serrations of the serrated edge are no more than 2mm in height and separation. ### Claim 4 (depends on 2) The method of claim 2 wherein serrations of the serrated edge are between 1and 3mm in separation. ### Claim 5 (depends on 1) The method of claim 1, the detection plate further comprising: one or more fasteners operable to removably affix the detection plate to hair of the person, such that a person using the detection plate can release the detection plate while removing a louse egg sac from the hair of the person. ### Claim 6 (depends on 1) The method of claim 1 wherein the detection plate is substantially white in color. ### Claim 7 (depends on 1) The method of claim 1 wherein the detection plate is substantially rectangular in shape and is at least 8 cm in width and in length. ### Claim 8 (depends on 1) The method of claim 1 wherein the detection plate has a matte surface. ### Claim 9 (depends on 1) The method of claim 1 wherein placing the multiple hairs of the person in front of the detection plate includes placing a layer of hairs, the layer being no more than 3mm in thickness. ### Claim 10 (depends on 1) The method of claim 1, further comprising: manipulating the multiple hairs during the viewing of the multiple hairs, the manipulating including at least one of rolling, shifting, and/or sliding the hairs over the detection plate. ### Claim 11 (depends on 1) The method of claim 1 wherein viewing the multiple hairs includes scanning regions of the detection plate in discrete steps and not in a continuous motion. ### Claim 12 (depends on 1) The method of claim 1 wherein removing the louse egg sac includes cutting the one hair off of the head of the person. ### Claim 13 (depends on 1) The method of claim 1, further comprising: removing hairs from the person, the removed hairs attached to lice egg sacs; collecting the removed hairs in a substantially white container; determining a number of lice eggs removed by counting the removed hairs and/or attached lice egg sacs; and recording the determined number of lice eggs. ### Claim 14 (depends on 1) The method of claim 1, further comprising: performing the method over substantially all of the hairs of the person. ### Claim 15 (depends on 1) The method of claim 1, further comprising: treating the hair for live lice on one or more days; and performing the method on multiple days over a period of time that is at least one week in length. ### Claim 16 (depends on 15) The method of claim 15, further comprising: after the performing the method on multiple times over the period of time, examining hairs of the person using the detection plate to determine whether or not lice or lice eggs are present. ### Claim 17 (depends on 16) The method of claim 16, further comprising: if it is determined that no lice or lice eggs are present, determining that the lice infestation has been successfully treated. ### Claim 18 (depends on 16) The method of claim 16, further comprising: if it is determined that lice or lice eggs are present, re-treating the hair for live lice on one or more days. ### Claim 19 (depends on 16) The method of claim 16 wherein the detection plate includes a serrated edge, and further comprising: placing the serrated edge of the detection plate against the head of the person and adjacent to roots of the multiple hairs; and fastening the detection plate to hairs of the person.
