Head Lice – Causes, Symptoms, and Best Treatments - #7049

Head lice are small parasitic insects that live on the scalp and feed on blood. They lay eggs (nits) close to the hair shaft, and when these hatch, the lice grow into adults, causing itching due to their bites. The itching is a reaction to the saliva lice inject while feeding, which can lead to discomfort. It's possible to have lice without noticeable symptoms, especially in the early stages. Lice spread easily through direct head-to-head contact, which is why schools and daycare centers are high-risk areas. They can also be transmitted through sharing personal items like hats, combs, or pillows, though this is less common. If one family member has lice, it's important to check everyone in the household and treat those who are affected. When it comes to treatment, over-the-counter shampoos containing permethrin or pyrethrin are commonly used. However, some lice have become resistant to these treatments, so it’s essential to follow the instructions carefully. Natural remedies like tea tree oil or coconut oil might have some limited effectiveness, but they are generally not as reliable as approved treatments. I recommend carefully combing through your child’s hair with a fine-toothed lice comb to remove any nits and lice. You may need to repeat the treatment in a week to ensure all lice are gone. To prevent reinfestation, wash any clothing, bedding, or personal items that have come into contact with lice.
