How often can you use lice shampoo?

Answer 1

You must follow the instructions on the bottle. First of all realize that there is poison in those shampoos and they are harmful to humans.
10 minutes is the maximum time alotted for the lice shampoo to remain on your head.
I had a lady tell me that her pharmacist told her to leave it on for half an hour. She ended up with central nervous system problems and head ache that lasted 5 months.
She was being treated by her doctor for detoxifying her system.

You must then wait 7 days before you can use it again.

My advice is: dont use it.

I found an incredible product. You can learn all about it at:

Answer 2

Well if it's the same treatment and you use it a second time an it didn't kill lice the first time idk why it would work the second time. Try a new treatmet. Or simply shave your head.
