Can I use a shampoo treatment as a preventive measure if someone around me has lice?

Good morning, ma'am,

Current treatment options are not indicated or recommended as a preventative measure. We will only treat if lice are found on your scalp.

Lice will not jump from one person to another, contamination occurs through direct contact, for example with a shared pillow or hat.

Sincerely,

Tom Samaha, pharmacist
