What are the best products for curly, thick, frizzy hair?

I was wondering what is the best products out there for my type of hair; this includes mousse, hair spray, shampoos/conditioners, pomades, deep conditioners, serums and maybe more? You get the idea though lol. And is a flat iron really good for my hair, cause I was thinking of straightening it but don't want to pay $300-600 for a chemical straightening treatment. Thanks. I would like something that would get rid of flyways and high humidity/static if possible. I am sorry I know this a lot to ask but I have really bad hair.

Hi!

I naturally used to have very curly/frizzy hair...for some reason after high school, it turned more wavy and tame.

When I had uncontrollable frizz (which was often, living in South Florida), I used a couple of products.

The first one is Aussie brand leave-in conditioner called "Hair Insurance". It's only a few dollars at your local drugstore. You spray it in after the shower and it helps moisturize your hair.

Then, I used a gel called Garnier Fructis Wet Shine Gel. You put it in when your hair is starting to dry (after the leave-in conditioner) and brush. Then I used a flat iron. It was perfect. (You can find the gel at your drugstore for fairly cheap as well.)

Good luck!
