### How to Treat and Prevent Head Lice Head lice can be a nuisance, but they are not a serious health threat. Here are some effective ways to treat and prevent them: #### Treatment Options 1. **Over-the-Counter (OTC) Treatments**: These are usually the first line of defense. Products containing permethrin or pyrethrins are commonly used. 2. **Prescription Treatments**: If OTC treatments fail, a doctor may prescribe stronger medications like benzyl alcohol (Ulesfia). 3. **Manual Removal**: For children under 2 months, or if you prefer a chemical-free method, use a fine-toothed metal lice comb to manually remove lice and nits. This should be done every 3-4 days for three weeks. #### Steps for Manual Removal 1. Wet the hair and part it into small sections using hair clips. 2. Use a magnifying glass and a fine-toothed metal lice comb to go through each section of hair. 3. Wipe the comb on a wet paper towel after each pass. 4. Repeat this process every 2-3 days for 2-3 weeks. #### Preventing Reinfestation 1. **Check Close Contacts**: Make sure to check and treat anyone who has been in close contact with the infested person. 2. **Clean the Environment**: Wash bedding, clothing, and personal items in hot water. Vacuum the living areas thoroughly. 3. **Avoid Sharing Personal Items**: Do not share combs, hats, or other personal items that come into contact with hair. #### Natural Remedies Some people use natural remedies like rosemary, tea tree oil, and lemongrass. While these are not FDA-approved, some believe they can help. However, more research is needed to confirm their effectiveness. By following these steps, you can effectively treat and prevent head lice.
