Yuck! Nits/headlice just make you feel yucky and dirty hey...even though you know they love clean hair.

My DD got headlice and nits last year for the first time. she made it all the way to year 4.
Once we were sure we finally got them all, I searched on here to find what other people were doing and made up a spray bottle of water with a little bit of lavender and tea tree oil (think i did a capful of each) and DD has been spraying that on her hair since. Luckily we haven't had any back since then. She just sprays in on before she brushes her hair for school.

Hope you can get rid of them soon
