How to detect them?

The head louse stings the scalp and feed himself with blood which causes itching. Children scratch their heads a lot. While observing carefully the scalp of your kids, you will notice small grey bugs (or red if they just ate), they are lice, and some oval white dots, they are nits.

Be careful. Don’t mistake nits with dandruff. Nits hold tightly onto the hair and it is hard to remove them.
