My 4 years old daughter has lice in her head what medicine should i give to her to get complete rid of it??

A. Mediker shampoo you can use and to initiate you should use it every day for a week hopefully this is going to help in reducing it and then you can use it once and two or three days depending upon the need so that is going to be a good option for you to proceed with that is how you should use it initially
