Synopsis of Lice

Lice are tiny parasitic insects that feed on human blood and infest the scalp, body, or pubic area. Infestations are common, especially in school-aged children, and spread easily through close contact or shared personal items. While lice are not dangerous or disease-carrying, they cause itching, skin irritation, and social discomfort.

Types of lice:

  • Head lice: Most common; live on the scalp and hair shafts.

  • Body lice: Live in clothing seams and move to the body to feed.

  • Pubic lice: Infest coarse body hair in the groin, armpits, chest, and sometimes eyebrows.

Symptoms include:

  • Intense itching, especially behind ears or at the nape of the neck

  • Red bumps or scratch marks

  • Presence of nits (eggs) attached to hair shafts

  • Crawling sensation on skin

  • In pubic or body lice: visible lice and inflamed skin

Transmission:

  • Person-to-person contact (especially head-to-head)

  • Shared hats, brushes, towels, bedding, or clothing

  • Sexual contact (in the case of pubic lice)

When to see a doctor:
If over-the-counter treatments fail, if skin becomes infected, or if lice recur frequently, medical treatment may be needed. Diagnosis is typically visual and may involve a fine-tooth lice comb or magnification.

Natural remedies for Lice

Wet-Combing: Use a fine-tooth lice comb on damp, conditioned hair daily to remove lice and nits.

Wash Bedding and Clothing in Hot Water: Dry on high heat to kill lice and eggs.

Vacuum Furniture and Car Seats: Reduces reinfestation risk.

Avoid Sharing Personal Items: Combs, hats, and towels should not be shared.

Use Natural Oils (with caution): Some people try diluted tea tree oil or neem oil for lice—only if skin is not sensitive.
