How not to get lice from a friend? - in detail

Lice spread primarily through direct head‑to‑head contact, but shared items such as combs, hats, scarves, or pillows can also transmit eggs. Understanding the pathways of transmission informs effective prevention.

Maintain personal hygiene that reduces the likelihood of infestation. Regular washing of hair with shampoo removes debris that could conceal eggs. Use a fine‑toothed comb after each wash to separate strands and expose any nits. Keep hair tied back or in a short style when close contact is anticipated, limiting the surface area available for lice attachment.

Separate personal accessories from those of peers. Store combs, brushes, and hair ties in individual containers. Avoid borrowing or lending headwear, helmets, or hair accessories. If sharing is unavoidable, disinfect items with hot water (minimum 130 °F) or a lice‑killing spray before and after use.

Clean the environment to eliminate stray lice and eggs. Vacuum carpets, upholstered furniture, and car seats daily. Wash bedding, towels, and clothing worn by the potentially infested individual in hot water and tumble‑dry on high heat for at least 20 minutes. Seal non‑washable items in a sealed bag for two weeks, the period required for lice to die without a host.

Implement a monitoring routine to catch early signs. Inspect the scalp twice weekly, focusing on the nape, behind the ears, and the crown. Look for live insects, translucent eggs attached to hair shafts, or persistent itching. At the first indication of an infestation, begin treatment promptly and repeat the preventive measures listed above.

Key preventive actions:

  • Limit head‑to‑head contact during close interaction.
  • Keep hair clean, combed, and, when possible, short.
  • Use personal grooming tools exclusively.
  • Disinfect shared accessories with heat or approved chemicals.
  • Perform regular environmental cleaning of fabrics and surfaces.
  • Conduct routine scalp examinations for early detection.
