Is using a lice shampoo more than the once every 7 days dangerous?

My daughter contracted lice from her cousins and we are trying to be proactive about it. Ca we use the lice shampoo more than they recommend, like after 2 days, or is it really dangerous??Is using a lice shampoo more than the once every 7 days dangerous?
Side effects may include temporary itching or tingling The most frequent side effect of lice shampoo is itching, which is also known as pruritus. This condition is most often a result of the scabies or head lice infestation, and may be heightened after treatment. Oral antihistamines and/or topical corticosteroids can help relieve the itchiness.





When using the 5% cream form of permethrin for scabies, some patients report a mild burning or stinging sensation, mild temporary itchiness, tingling, numbness, mild erythema, edema or rash. The 5% lotion form (for scabies) can lead to similar side effects.





Frequent use will increase you chances of having these side effectsIs using a lice shampoo more than the once every 7 days dangerous?
You should wait the recommended 7 day period. Using after just 2 days is overdoing it. Any lice she may have will likely not have hatched yet and the shampoo does nothing to kill the nits. Get a fine comb and some good lighting and get nit picking. That's what really gets rid of headlice.
