Step 1: Use the LiceMeister comb on clean, damp and untangled hair. Comb through the entire head. Examine the comb for lice and nits. If lice or nits are detected, go to step 2. Step 2: Divide and clip the hair into sections. Taking a small amount of hair at a time, place the comb against the scalp pulling the comb completely through that section of hair from the root to the end. Step 3: View instructional video on combing. Cleaning the comb: Use the LiceMeister Comb Cleaner to dislodge and remove lice, nits and hair debris from the comb. The LiceMeister Comb can be dropped briefly in boiling water between use on different individuals and before storage.
