How do i tell her to get rid of her head lice?

HEAD LICE SHAMPOO: See your pcp who can prescribe head lice shampoo.It takes longer to get rid of nits even though lice are killed by shampoo because they are firmly attached to hair shaft.

Got to address it.: Well, if she doesn't get rid of them, she will pass them on to you & others. They are contagious. Please point out to her that you care about & for her but not for her lice. Here is info you can provide to her. Tx of lice requires accurate identification of nits & / or lice. A pediculicide is usually used- otc like nix (permethrin) or rid or prescription meds like lindane or malathion. Work carefully through.
