@Txtoast :
It is strange. You can go to almost any store and buy a treatment kit yourself.
I've had them twice- once as a child and once as an adult so yes, they can be a problem. Especially if you have long, clean hair that is free of styling products/oils.
As an adult, I went to a doctor because I thought there's no way I have lice, though my scalp was itching badly. Damn doctor didn't diagnose me with lice. She said it was just dry scalp. That was 20 years ago! Scary how a "doctor" misdiagnosed such a common problem when we were already in the year of 2001.
I didn't know I should've been spraying my hair with hairspray and keep it tied up while working in a daycare. Friend who worked for a gov't run daycare when we were in high school told me of this tip afterwards.
