Lice solution needed

I recently found out I have lice. I bought a product at Walmart that has a lube consistency. I put it all over my head, showered and used a lice comb in the shower, then after. I did it twice. I feel like I got most out because my head isn’t as itchy. Today, I was looking at my hair and there’s dead lice all over

(Blurry pic but they’re there):

I combed my hair again today and there’s still some alive. Anyone know of any shampoo that actually works. Also how can I actually remove the hanging lice w/o having to comb it out because the comb I was using wasn’t taking all of them out. Or is there a comb you’d recommend ?
