Lice help!?!?!?

I am currently 22 years old and have never had lice until last year. I went on a trip with a youth group I was in and came back itching. I thought maybe it was just my psoriasis acting up (I have scalp psoriasis), but after a few weeks I went to go get my hair cut and was told by the girl that I had lice. I was completely mortified! I slunk over to the drug store with my mom and got some Nix. I followed the directions and did everything right but they kept coming back. It is now over a year later and have tried EVERYTHING to get rid of them. I don't know where they are coming from! I have sprayed and vacuumed the bed, the couches, and my car. I am at my wits end! I feel like I want to shave my head but I can't because of the psoriasis. I can't seem to fight them. I called the doctor and got a prescription cream but I have to leave it on for 14 hours and I have school in the morning...what should I do?!?! PLEASE...I AM BEGGING YOU FOR HELP...ANYTHING!!!!

    There definitely are prescription meds that do not have to be left on that long.  I don't understand what your doc was thinking.  One of the latest, most effective one is mentioned here - http://www.kvue.com/news/health/kids-doctor/129441173.html.   It only needs to be left on 10 minutes and is twice as effective as Nix.
    Good Luck!!

It is also a matter of washing the sheets and pillow cases all the time because the eggs are left on them.You have to comb relentlessly the little charmers dont like being disturbed so lots of combing with the tooth comb washing that comb after use .

you can also store anything not washable (like stuffed animals) in a black plastic bag for 10 days.  That will break the cycle as they will die with no ability to feed.
