Dear mikuta,


Greetings and thankyou for using justanswer!


The cream contains permethrin (5%)and is usually applied for Maximum upto 8-14 hours on the body. You should wash it off with shower or bath after the maximum recommended period. Though on scalp only 1% cream is applied and 10 minutes are sufficient to kill the lice.

NOTHING will happen if you rinse after 1 hour.


The pruritis may be the side effect and is usually upto 2 weeks after the application.The eyes should be cared of while applyiing.
