I don't know if this has been mentioned, but my dd is b-racial and got it last year. OMG we battled those suckers for 3 weeks. Her hair is very thick and very curly so the knit combs were impossible, I had to just hand pick them one at a time.
But this year, once winter hits we will be putting a small amount of pink oil moisturizing lotion in her hair. Her hair really doesn't need this, but supposedly the lice don't like that stuff so they stay away. Once I started using it last year she didn't have any further problems.
