OP if you want something that actually works, you'll need something stronger, if you've got a real frizz problem.
I use Brazilian hair straightening from keratin kits. You can get it on Amazon. It's more of a smoothing that straightening tbf, which is more what I wanted. If you've got fine, greasy hair, don't use it though. It's essentially constantly moisturising your hair, so you can imagine that if you have greasy hair, it's not going to do you any favours.
It's a bit time consuming initially, but after that, it can last up to 6 months and I don't even need to blow dry my hair now. It used to take an hour to blow dry and straighten my hair, so it was a bit of a god send for me.
