Frequently Asked Questions(FAQ)
Are lice eggs alive after treatment?

Can I use lice shampoo 2 days in a row?
Do not use more than one head lice medicine at a time without asking your doctor. Do not rewash hair for 1 to 2 days after the lice treatment. It may reduce the effectiveness of the lice medicine.
