Dandruff is dull, flaky and loose enough to fall out. The nits are shiny and firmly attached to the hair. That is why it is so difficult to get rid of them. It is very important to get treatment for lice and nits as soon as you find them. People who have had lice for a long time begin to feel unwell.
Head lice can cause other, more serious infections if they are left untreated.
Treatment is in the form of either a shampoo or a lotion, which are available from your local chemist. Shampoo is applied in the normal way. Lotion kills the lice and nits in a few easy applications. It is rubbed into the hair and scalp and then left to dry naturally, because using a hair dryer can destroy it's effectiveness. After waiting a specified time the hair can be rinsed in the usual way.
