Steps to Eliminate Head Lice

Head Lice Preventative Method

Schooltime® Patented Coconut Derived Emulsion: Works by suffocating or immobilizing lice. Non-toxic, hypoallergenic, pesticide free.

Family Shampoo: After hair is cleared of lice, clinical studies have shown using Schooltime lice shampoo at least 2 X per week on wet hair as a regular family shampoo (thoroughly lather into wet hair for 5 minutes and rinse) would help prevent re-infestation during times of high exposure. If desired, this can be followed by use of a favorite hair conditioner or other cosmetics.

Ensuring the Home is Lice-Free

Head lice cannot survive long once separated from the human scalp. They require frequent blood meals—typically every 4 to 6 hours—and a warm environment close to the skin to stay alive. According to the Centers for Disease Control and Prevention (CDC), lice usually die within 24 to 48 hours after falling off a host. This means that while lice can briefly survive on items like bedding, towels, hats, pillows, or plush toys, they do not linger for days waiting to reattach to a new head. Thorough cleaning—such as washing items in hot water, drying on high heat, or vacuuming—is usually sufficient. Once the lice are off the host and the environment cleaned, the infestation cycle is broken. At that point, it’s simply a matter of routine housekeeping, not ongoing transmission risk.

By following these steps, you can effectively break the life cycle of head lice and ensure your home and family are lice-free.
