Kits vary: some are labeled for “All ages,” while others list minimum ages such as “1 year and up,” “2 years and up,” or “6 years and up.”
Most kits include a fine-tooth lice removal comb. Many also include home sprays, magnifiers, grooming combs, and small brushes for debris removal and cleaning.
Some kits include inspection aids such as magnifiers and debris-cleaning brushes to help locate and clear nits, eggs, and lice from the hair and combs.
Common warnings include eye irritation notices, instructions to keep products out of reach of children, age restrictions such as “Not for children under the age of two,” and choking-hazard notices for small parts in comb kits.
Kits come in a variety of forms: shampoos and liquid treatments for in-hair use, sprays for home or leave-in prevention, and some kits combine multiple forms in one package.
