My 7 year old daughter got hair lices and because of her I also got them... After consulting Doctor, I applied her Perlice lotion as directed and reapplied after 10 days... Combed hairs with lice comb so many times ... but on the second application day also , many lices came out of her and my hairs... Should be apply it third time or what to do... I still see many eggs and they are not coming anyhow from comb ... What to do.. Should we get the head shaved ?
