Curly hair products for humidity?????

I’m going to a wedding in a few weeks in Michigan and it’s gonna be HOT and HUMID and I have a mix of 2C and 3A hair. Mainly 3A and honestly, my hair isn’t in the best shape right now due to some health things.. it hasn’t been in a long time. It used to be long but then I gave it a big and greatly needed chop and it hasn’t been able to grow back long and healthy ever since. Just seems like it breaks and splits and dries up and ugh.. anyways.. I just want good healthy product suggestions to put in my hair for when I go.

I need products that will:

1) get rid of frizz

2) smooth out my hair cause imma do smooth curls with a curling iron instead of have my natural hair because it doesn’t look the best right now anyways..

3) keeps my style all day because the wedding is all outside 😂 and I don’t want my curly hair to start to come back a couple hours in and ruin the work I’ve done.

Anyhow, product suggestions would be greatly appreciated... wish I could wear my natural hair.. 😭😩
