CHEMICAL TREATMENTS BEAT NITS
Head lice are common in children, but they're essentially harmless and can be killed with chemical treatments, say researchers.
A review paper published in the British Medical Journal (BMJ) looked at the problem of head lice - parasites that infest scalps and usually target children. Although they're common and frequently spread between children, common misconceptions about the tiny creatures still exist. The good news is that the parasites are essentially harmless and once detached from the scalp and hair, they die.
A review of chemical treatments found that products such as Malathion, Lindane, Permethrin and Pyrethrins work effectively and normally kill head lice. Herbal treatments, such as tea tree oil, and aromatherapy are popular, but their effectiveness hasn't yet been studied scientifically. Likewise, the effect of combing to remove louse eggs hasn't been confirmed.
According to the report, infection is only spread between people who have prolonged head-to-head contact and treatment should only be commenced if live lice are found. Cutting hair or tying it back isn't helpful and can increase the nits, rather than ward them off.
Even if your child has signs of eggs in their hair, it doesn't mean they'll necessary progress to a full-blown nit infestation. In fact, less than 20 per cent of children in this situation become infested.
