It turns out to be a very embarrassing situation when someone tells you that they have spotted lice in your hair or your child's hair. While you can still take some effective steps and deal with the problem on your own, your child may not be able to do so. Besides, you can never leave children to sort this problem themselves, because one day you might clean their heads and get it free from lice, the second day they will play with some kid in school having lice in his/her hair, and will come back home in the same situation as the previous day. Therefore, children need a constant watch and supervision over them.
Having lice in one's hair could be a result of many things. Maybe your child is involved in a lot of water activities such as swimming, and does not give enough time to his/her hair to dry off well. For small girls, many parents often forget to open their pony tails after swimming to let their hair dry, and that often causes lice. Other factors could be an unclean and unhygienic style of living, with unclean bed sheets and pillows, or not washing one's hair frequently enough etc.

There are some basic home remedies that one can follow to get rid of this problem. These home remedies ensure that you do not have to subject your hair to the torture of high chemical shampoos that take lice away, but damage your hair completely. With home remedies, you can maintain the natural health of your hair, and also get rid of the hair lice.
One of the most tried and tested remedies for reducing hair lice is to make a paste of lemon juice and garlic paste. You should apply this on your scalp for around 30 minutes. Do this twice a week before washing your hair, and you will start to see the results soon. Another alternative is to oil your hair with olive oil, and then wash it. Some people also apply egg yolk for around 20 minutes before head wash.
There is another method that you can try which involves mixing equal amounts of vinegar and water, and then rubbing it on your hair for around 2-5 minutes. Then wash it away with cold water. Do it once daily.
It is goo to keep a head lice comb handy at your home at all times. Cleaning the lice frequently with this com helps to prevent further lice from growing on your hair. There are special combs for the nits, also known as lice eggs. Use those combs too frequently to get rid of the nits as well as the dead lice. The nits have a tendency to grow into lice soon, so you need to ensure that you are cleaning the lice and the nits both.
Overall, maintain a clean scalp at all times, by washing it frequently enough and letting the hair dry off well. Never tie wet hair, and keep it away from dirt and other unhygienic factors.
