Label ages vary by product; examples include "6 months and up", "1 year and up", "2 years and up", and "6 years and up."
Descriptions list varied approaches: a prescription-strength active ingredient (ivermectin 0.5% lotion), salt-based/homeopathic formulas (sodium chloride), and essential-oil blends (tea tree, peppermint, rosemary) used to repel or treat lice.
Common warnings include keeping products out of reach of children, noting eye-irritant risk, specific age restrictions (for example, not for children under two or labeled ages like 6 months+), and directions to consult a doctor if pregnant or nursing for some formulas.
Product claims vary: some advertise instant or "kills on contact" effects, while others describe short timed treatments that act in about 10 minutes.
Many listings include a fine-tooth or professional lice comb to help remove dead lice and nits; a few products also state that no nit-combing is required after treatment.
Several products emphasize pesticide-free or non-toxic approaches, including homeopathic or sodium chloride–based formulas and pesticide-free shampoo treatments described as non-toxic and hypoallergenic.
