Is it dangerous to use Lice shampoo more often than the recommended 7 to 10 day interval?

Wait a few days and get the [-{{Nix}}-] brand treatment for her. Nix is much better than Rid. Nix kills the lice and the eggs and last to prevent for 2 weeks. Do shampoo her with the Rid first to kill any lice that may have hatched out. before you use the NIX. I also recomment that you get a product that helps dissolve the glue that the lice use to cement the eggs to the hair. I know this gets kinda expensive to get all 3 products but it is worth it to prevent it from coming right back. Use the rid, then the nit removal procduct, then the NIX 3 times in 6 weeks at 2 week intervals making sure you get all nits out and you should be rid of this plague. The eggs are what keeps reinfecting the poor children.
