Lice and dandruff are two conditions that attack the scalp. Both of them make the scalp itchy and appear white spots on the hair. Sometimes, it's difficult to distinguish whether you have dandruff or just curse just by looking at it and relying on itching on the scalp. For this reason, recognize further the differences between these two conditions.
Difference between lice and dandruff
What is a tick?
Head lice are infectious parasites that usually attach to the scalp and hair shaft. Pediculus humanus capitis is the name of the parasite that causes head lice. Generally, head lice consist of three types, namely:
- Eggs (nits), usually small white spots attached to the hair shaft.
- Nymphs (young adult fleas), small brown light insects that hatch from eggs.
- Adult fleas, usually larger in size than nymphs, about the size of sesame seeds and dark brown.
About 6 to 12 million children from 3 to 11 years usually have head lice. Head lice survive by sucking blood from the scalp they have left. Lice saliva when sucking is what causes irritation to the scalp and finally makes the scalp itchy.
What is dandruff?
Dandruff, also called seborrheic dermatitis, is a chronic scalp condition characterized by peeling the skin on your scalp. Dandruff that sticks to the scalp often looks like scales. Usually, dandruff will fall out when you scratch it.
Dandruff can cause itching because the condition of the scalp is too dry. Dandruff is not contagious, even if you borrow personal items such as combs, hats or pillows. Even so, people who dandruff may feel embarrassed because the scalp looks dirty and scaly white.
Causes of lice and dandruff
Where do fleas appear?
Lice are usually transmitted from people who have fleas in their hair. Direct head contact or using a comb, hat, towel, and pillow alternately can be a means of infestation to spread. If in a house there is one person who has lice on his head, usually all family members will get infected. Head lice spread from human to human. Fleas in pets are different from head lice in humans. So that pets cannot transmit the fleas they have to humans.
Having head lice does not mean you have a dirty hair or head. Lice will live even in hair that is diligently cleaned. Head lice do not spread certain diseases, but having head lice can make your scalp very itchy. If you scratch the scalp continuously, this condition can make the scalp hurt until it causes infection.

The white spot is a manifestation of hair eggs. If flakes of dandruff will fall easily if combed, the egg lice stick tightly. Lice will only be released if you release it slowly from the hair shaft.
For most teenagers and adults, dandruff is easily recognized by the appearance of white flakes on the scalp and hair. Sometimes, if you use a dark shirt, flakes of dandruff will appear on your shoulder. Dandruff in children is characterized by scaly and crusty scalp.
