Spotting the Culprits

Head lice are about the size of a sesame seed and can be hard to see. They lay eggs (nits) that stick to hair shafts. To check for lice, part the hair and look closely at the scalp, especially behind the ears and near the neck. You may see tiny grayish-white eggs or crawling insects. A special fine-toothed comb can help detect lice more easily than just looking.

Myths vs. Facts

Contrary to popular belief, having head lice doesn't mean you're dirty. Lice can infest anyone, regardless of cleanliness or social status. They don't jump or fly, but spread through direct head-to-head contact. Sharing hats, brushes, or towels can also spread lice, but this is less common. Lice can't live long away from a human scalp, so don't worry too much about carpets or furniture.

Treatment Options

There are several ways to treat head lice. Over-the-counter products containing permethrin or pyrethrin are common first choices. These work by killing the lice. Some prescription treatments are available for tough cases. Another option is 'wet combing,' which involves carefully combing out lice and nits with a special comb. Whatever method you choose, it's important to follow instructions carefully and often repeat the treatment after a week.

Prevention is Key

While it's hard to completely prevent head lice, some steps can help. Teach children not to share personal items like hats or hair accessories. Regular head checks can catch an infestation early. If someone in your household has lice, check everyone and treat those affected at the same time to prevent reinfestation.
