So I've read the Tea Tree oil is effective in thwarting off those little buggers. Here's an article:
Anyways, I'm using it as a deterrent. I've in the past put it in their shampoo. But tonight I forgot and blow dried Olivia's hair. Too late for the shampoo, so I decided to dilute it into a spray bottle. I don't want straight oil on my daughters hair but I don't want to send her defenseless. So... I diluted it with water. Yes- oil and water. Not sure how it would work obviously they separate. But, I was able to figure a quick solution.
I vigorously shook the spray bottle with a 4:1 water: oil mixture. Sprayed immediately on her hair, as I would hairspray. It smelled of Tea Tree oil which works for me!
I'm not a scientist, just a mom desperate to not EVER have lice. This is my personal way to put my mind at peace. If you're like me, give it try- can't hurt.
I just got my bottle at the local Walmart by the vitamins.
Good luck!
