Lice Shield Lice Repellent shampoo and conditioner does not work. Within 3 days of beginning to use this shampoo my hair went very dry, I got really bad dandruff and my head was severely itchy. It doesn't even repel lice like it claims to. Lice Shield costs $9.48 at Walmart Canada for a travel sized bottle, so not worth it. I would recommend just using regular shampoo and conditioner, it would probably work better anyway.
