I originally tried the Walmart brand and didn't make a bit of difference. Luckily I had bought this as a back up option. It makes a huge difference in getting the eggs out of their hair. I would've had to buy that separate otherwise so it saved me money.
We got rid of lice in all 4 of our kids hair combing their hair with this everyday. No chemicals had to be used it pulled out all lice and the eggs. We also washed their bedding daily for 1 week and bagged their stuffed animals 3 weeks to be sure.
Great for stripping your hair of tangles and dandruff. My daughter has thick natural hair so it takes some time
