I'm not sure how far to take my de-head-lousing treatment, as the kid I babysit for has lice.?

I only came into contact with her today, and it wasn't super close or anything. She had lots of eggs, so I went ahead and used the lice shampoo, Rid, and I'm going to straighten my hair as soon as it dries enough. I'm also hot washing the clothes I wore today. Is that enough?
