Sometimes, itching becomes more complex and even causes various scalp infections.  So, if you really want to give your child a comfortable sensation, then you have to learn different methods of lice treatments. But before that, it is good to have a look at head lice life cycle to know the background of their growth process.

Head lice life span is around 40 to 50 days and you can easily go for a valid treatment before their increased production. There are three different stages in their life cycle – Eggs, Nymphs and Adults, so without any delay, let’s have a look at all three stages of head lice growth:



Eggs are also known as nits or ova. When the female louse lays the eggs along with waterproof glue like substance, they get cemented into the hair shafts near the roots. These eggs are of small size just like a poppy seed and also difficult to detect because the color can easily blends with the affected child’s hair. They may vary in color from white to yellowish brown.

The eggs start developing and hatching around 10 days later. Sometimes, people consider them dandruff and sand flakes by mistake and remain carefree from the consequences. Another important thing is that eggs and their casings cannot be removed easily. You should comb them out carefully with the help of a fine-toothed comb.

An average hair growth is about ½ inch per month and lice will be hatched in two weeks. So, if you find any egg or nit more than ¼ inches from the scalp, they are most likely hatched or dead. Many schools also have a “No Nit Policy” that means if a child has lice, he is not allowed to admit in the school till all the lice are gone. By this, other children can be prevented from the natural lice growth.



When the louse hatches into the hair it is called a nymph. It is hardly visible to the naked eye and cannot be reproduced because of its incomplete development. It further turns into the adult louse after 12 days approximately.



This stage is the last stage of head lice life cycle. When a nymph turns into an adult louse, it can hatch up to 4 -10 eggs per day. This stage lasts around 28 days and female louse lays around 125 eggs. This adult louse is the cause of excess production of eggs; therefore, it is good to search for a further treatment.

So, this is all about head lice life cycle. Read out the above mentioned stages and find out clearly which stage is the cause of problems for your child. Once you detect the stage, go for an immediate treatment. Ask your trichologist to prescribe a workable solution to your child so that it will work out in the shortest possible time.
