Head lice are found in children from all backgrounds. They are very contagious and can spread easily. Taking action quickly is the best way to prevent head lice from spreading to other family members. Parents need to remain calm so that children will cooperate. Head lice need human blood to grow, develop and lay eggs. Feel free to call Licenders with any of your head lice questions 212-759-5200. We are here to help.
