Anyone dealing with an active head lice infestation — parents treating kids, or adults treating themselves. No hair type restriction, and no experience needed beyond patience: it works best on wet, detangled hair combed in small sections.

It's an inexpensive, reusable way to physically pull lice and nits out of the hair, and it's the recommended companion to any chemical treatment rather than a replacement for one.

• Wet and detangle the hair first — lice combs work poorly on dry or knotted hair
• Divide hair into small sections
• Draw the comb firmly from scalp to ends, checking the teeth after each stroke
• Rinse the comb in warm water between strokes and wipe dry
• Repeat over several days to catch nits as they hatch

• Two tooth-spacing sizes cover both a heavy first pass and finer follow-up combing
• Reusable for the full length of a treatment course
• No chemicals involved, so it's safe to use as often as needed

The tradeoff is that combing is mechanical, not curative: it won't kill lice on its own, and it typically takes several sessions over a week or two to fully clear an infestation, especially newly hatched nits.
