Lice spread primarily through close contact or sharing personal items like hats, combs, and hairbrushes; they are not caused by poor hygiene and can affect anyone, regardless of cleanliness.

Preventive measures include avoiding the sharing of personal items, conducting regular hair checks, educating children about avoiding head-to-head contact, and using preventive products such as natural or over-the-counter sprays.

Treatment options for lice infestations typically involve over-the-counter shampoos or lotions containing permethrin or pyrethrin, manual removal with a fine-toothed lice comb, prescription treatments for severe cases, and some home remedies like tea tree or coconut oil.

Re-infestation is possible if close contacts or shared items are not addressed, and intense scratching can lead to bacterial infections requiring antibiotic treatment.

Environmental cleaning is important; washing bedding, clothing, and shared items in hot water can help prevent re-infestation since lice cannot survive long without a host.
