Industrial Sized School Supply

I cringe whenever I hear about a student having lice. I cringe even more when I see pictures on Instagram of Danielle's class doing activities where they are sitting back to back with their heads touching. Seriously. I started buying this last year. I don't know if it works or if she just hasn't been exposed since she started using it, but it lessens my panic attacks some. (She uses regular shampoo and detangler.) I should have put something in the picture for perspective. This bottle is huge!
