Lice (Head): Brief Version
What are head lice?
Head lice live only on human beings. They can be spread quickly by using the hat, comb, or brush of an infected person. The nits (eggs) normally hatch into lice within 1 week. Your child probably has lice if:
- The nits (white eggs) are firmly attached to hairs. Unlike dandruff, nits can't be shaken off.
- There are gray bugs (lice) in the hair about 1/16 inch long. They move quickly and are difficult to see.
- Your child's scalp itches and has a rash.
How can I take care of my child?
Call your child's doctor during office hours if:
- The rash and itching are not gone 1 week after treatment.
- The sores start to spread or look infected.
- The lice and nits return.
- You have other questions or concerns.
